No question for me (although I'll be in the super minority ...again): Search: WWW. I dare you not to fall in love with him (and Scarlett)!

Every project of his, including Marco from MOtA 😅

He was the most charming in Search WWW, had the best scowl in EY, most lost in Dol Dol (why was he in this drama again?) , quite versatile in Alchemy (from one season I saw) and a fantastic cameo in Death’s Game.

I like Lee Jae-Wook but I didn't really like his dramas as main lead like Do Do Sol Sol La La Sol (he played one of the worst ML for me), Alchemy of Souls 1 was good but the second part was a disaster.

I really liked him in When the Weather is Fine and Search: WWW as supporting cast.

In Extraordinary You, his character had a nice arc (but I never had a second male lead syndrom).

I liked his roles the most in "Extraordinary You" and the second part of "Alchemy of Souls". Because both of these roles had something of a villain to them. Such roles suit him. If he ever played a full-blooded villan, a sexy villan, I would be very much in favor of such his role.

Lee Jae-wook has been a part of some very interesting shows; however, for me only perhaps, he seems to shine more in the supporting roles. This is not conclusive because I have only watched 3 of his projects so far, 2 of which I really loved he was either a supporting or a cameo role.

What I loved him in:
1. When the Weather is Fine (aka I'll Find You on a Beautiful Day) (Supporting cast)
2. Memories of Alhambra (a cameo/ supporting role)

What I found ok-ish:
1. Alchemy of Souls

He's a supporting character in Move to Heaven. I had no idea he was in it before I watched it and I was like hmm, that looks familiar haha

It's a sad one so be warned

Ok, so I know it's pretty universally disliked, and BOY did it go off the rails in spectacular fashion in the last 5-6 episodes, BUT... I really liked Lee Jae-wook in Do Do Sol Sol La La Sol. (*and I didn't hate that drama, either, although there are MANY THINGS that should have been fixed in the writing*). 🤷‍♀️

My main recommendation is When the weather is fine. His character was so cool.

He was great in Death's Game

I loved him in both parts of Alchemy of Souls. He had a great character arc across both series that I feel he played incredibly well for an actor of his age. His screen presence is compelling, and I agree with @OAsia that he would do really well with a "hot villain" role.

I've watched almost all his work, including the movies, except Memories of the Alhambra (I tried, but I just couldn't watch Park Shin Hye) and Kiss Sixth Sense. Let me rank them here based on how much I enjoyed the dramas over-all, and not how I felt about his characters (there were dramas where he did wonderfully, but it was the drama that fell short).
1. When the Weather is Fine
2. Alchemy of Souls 1
3. Extraordinary You
4. Alchemy of Souls 2
5. Search: WWW (and What's Wrong with my MIL!)
6. Move to Heaven
7. Death's Game
8. Do Do Sol Sol La La Sol (I'd rank this higher, but the last few episodes were awful. So maybe watch this, but stop at episode 13.)

I didn't include True Beauty because we was there for like 10 seconds. Haha..

Just like the Beabie Rec requester, I don't know if I like The Impossible Heir yet. To be honest I'm just watching because of LJW. But the FL is definitely turning me off, and the dad's wife is annoying.

I recall the feeling of “who is that???” 😳 at his first scene in WWW and then basically watching the remainder of the show hoping he’d show up every moment. It’s so great to have seen him shoot to stardom!

I have enjoyed Lee Jae-wook’s work over the years. I am not watching his current drama on Disney+ (TIH). AsianWiki list 13 drama series for LJW going back to 2018. I have watched and enjoyed him in four (in order):
1. JTBC’s WHEN THE WEATHER IS FINE (2020) (Viki US). My first LJW drama. At age 22 he beautifully played a character who was supposed to be 27 iirc. He was part of a great cast in that drama.
2. KBS’s DO DO (2020) (Netflix). Lol, LJW was NOT the problem. The writer and director were the problem. I enjoyed his performance until the now infamous ending. In an epilogue to episode 15 (2:47 remaining) there is a beautiful meeting (guy scene if you will) between LJW’s character Joon and pal Seung-gi (Yoon Jong-bin). That one scene made hanging in to the end worth it for me. Perhaps the most enjoyable scenes were the elder backstory scenes with LJW and Go Ara.
3. NETFLIX’s MOVE TO HEAVEN (2021). Overall a 5 star drama and LJW was terrific as (yes) a young boxer. He obviously trained. Both LJW and Lee Je-hoon’s physicality was excellent.
5. tvN’s ALCHEMY OF SOULS (2022). I enjoyed LJW’s performance but not enough to continue with the franchise.
Take your pick.

Among the shows he was in, liked him best in Search: WWW, while Alchemy of Souls S1 is a good watch for a LJW fan. But totally skip Do Do Sol Sol since its not worth your time.

I'm with @seon-ha and with the exception of "AoS," think LJW's performance in "WWW" is my favorite. But I also want to cast a vote for his cameo in "Kill Boksoon." He's on-screen for less than five minutes but it's such a pivotal moment in his character's life and he played every beat of it perfectly. Plus, this tiny role allowed him to display all his strengths. He was completely believable as the aloof, cold assassin who enters the scene, as well as the smitten guy who immediately fell for the even more aloof and colder woman he'd end up mooning over for the rest of his life. The fact that I even remember these few minutes in the movie as well as I do speaks to his immense talent and presence.

Sigh. Is it okay to NOT worship at the feet of LJW???

First saw him in Alchemy of Souls Part 1 and. . . ,meh. Of course, I began the drama because of Jung So Min, and I enjoyed him - along with several others such as Arin, Yoo In Soo, Oh Nara, Yoo Soon Jang. LJW was enjoyable, but I will never understand the adoration.

Which is okay because the world would be so very, very boring if we all agreed on everything.

We were discussing "chemistry" the other day, and I have to say, the weird things that Lee Jae Wook does with his hands in kissing scenes are the essence of chemistry. The hand motions (head cradling, chin stroking with thumbs. etc.) make the audience notice that he is bigger than the person he is kissing, they make her face look super small, they make him look extra caring, and it seems so natural. But just think about it--when is the last time someone kissed you and stroked your face with his thumbs? It's not a thing. But he makes his height and size into the most romantic thing in the world, like a boss.

Anyway, the other aspects of his acting are equally special and wonderful. I loved his sad, scheming yet dynamic second lead in Extraordinary You, a show I really loved. I thought he was good in Do Do Sol Sol La La Sol but if you haven't seen it, it's not worth it. Ugh. He contributed the most to Search: WWW, in that I wanted to see him on screen the most. So funny, adorable and cute! I also thought he was more than fine in When the Weather Is Fine, again showing character dynamism. I even liked him as the main lead in the weird but captivating Alchemy of Souls.

I think he's really a very fine actor and it amazes me that he did some of these roles when he was so young. He's got great comic timing and he makes choices that look like a person changing his mind. I feel like that's one of the hardest things to do on screen. I didn't realize how difficult until I started regularly watching TV in a language I don't know.
