I absolutely love this series. It's definitely one of the best (if not the best) Thai show I've ever watched, under every aspect: the writing, the plot, the acting, the characters. Everything is extremely well done.

I'll start by saying that if you're looking for a cute series to watch because you simply like to see two pretty boys kissing then this one is probably not for you. I saw way too many people complaining that Jack and Joke don't get together until way too late in the series, and that there's too much plot and not enough romance; but the point is that this show isn't a romance - sure, the romance is there and it's extremely important, but there's also a very heavy and important plot that is what makes the show move forward.
But, if you're looking for something different from the usual Thai drama, then this might be for you. Because Jack and Joker doesn't follow the usual Thai drama narrative structure and frees itself from all the classic tropes, both plot-wise and romance-wise.

The story deals with a lot of deep and different themes, and it touches upon them with care and attention: poverty, class difference, rich people and the power they hold are the main obvious themes of the show, tied directly to the main plot; but it's also a show about forgiveness, about family, about education, and so many other things it would be difficult to list them all here. Yet it manages to deal with them all in a complete way, nothing feels half-done or thrown in there just because. Frankly, the more I think about it the more I find new things to analyze and think about - it really gives you food for your thoughts.
At the same time, though, it's not a heavy show: the drama and heaviness of the story is perfectly balanced with some more goofy scenes, so it never feels heavy or too much to watch. It's heartbreaking in some aspects, it will make you suffer in some scenes, yes, but it will also make you laugh and in general give you a sense of hope - hope that things will be okay and that it's worth living despite everything that is wrong in the world.

Both Jack and Joke are fantastic characters: they're realistic and flawed as every human is, they make mistakes and they try to fix what they did wrong; both of them have a beautiful character arc that make them grown during the story. I could write whole essays about each of them and their relationship, really. The slow burn of their romance made me go crazy in the best possible way, which made the moment they finally get together all the more satisfying.

Yin and War are amazing, their performance in this show is simply perfect. We already knew they're great actors, but after watching this I'm not afrai to say they mightjust be the best I've seen. They really made the characters come alive in every little detail. War especially really shines a lot in this show: as Joker, he has to interpret a lot of different roles, and it's amazing to see just how different War carries himself when he's being Joke who's acting like someone else. Not to mention the dramatic scenes: no one can act a dramatic scene the way War does; be ready to cry, because when Joke cries it will be impossible not to join him.
Yin too is incredible. I'm so glad he got to act so many action scenes, because he's simply amazing at them; all the fighting scenes are so well done, I could watch Yin fighting for hours honestly. He said he prepared a lot for this role and it shows, because he did an amazing job. And he's way too good at crying too. The two of them together will make you cry, no doubt about it.
Do I even have to say anything about the kissing? Yin and War literally invented kissing and they sure gave it their all in this show.
Anyway it's not even just the two of them, literally every actor in this series is amazing and every character is perfectly written; they're not just background characters, they really are their own people.

So, it's really a beautiful show, from start to finish, I have already watched it twice and I will definitely rewatch it again and again in the future.
Frankly, I can't recommend it enough to whoever wants something different from the usual Thai BL (and even to people who don't usually watch BLs).
Yin and War made this show from scratch using their own money, and they did it for their fans. All the effort and love and care they put into it really shines through, and I couldn't be more thankful.
