I'm going easy on this with the rating because Atom and Kongthap are lovable for the most part and that is thanks to Gemini and Fourth and this series would NOT be popular without them and their following, so maybe I'm a bit biased too.
But they stretched 10 episodes of under 30 minutes to 12 episodes of about 45, including countless product placements that rarely blend naturally into the storyline. So the script and the characters are all over the place.
I liked the first episodes and I was waiting for them eagerly, but after the midpoint the quality dropped significantly. The second couple lacks any charm and their stories are bland or silly (like the She-Hulk episode, or whenever Mudmee listens to her idiot friends), her scary father, getting upset that Half didn't remember their encounter. Granted the original can be very silly, given it's a manga, but it's dense and it keeps you wanting more, not just feeding you bad writing.
As for the main couple, they improved Atom's love interest. He is much more open and gets in touch with his feelings pretty quickly, but then they lost their main conflict so they had to come up with all sorts of pointless stories to fill whole episodes. Of course some of them work and all episodes have at least one or two cute moments and the actors kind of take turns in being lovable. But Gemini was very wooden for most of the last episode, Fourth overdoes it sometimes (and it's not always cute) but he was directed to act like that, as seen in the BTS clips. Anyway that last episode was really pointless, you could tell they ran out of ideas and they were stretching it. The second to last was pretty thin too.
There's also a break in logic or the logic of previous episodes or disjointed scenes - maybe bad editing? Like in the stage play Atom just has to do the lead role a few minutes before the curtain, and suddenly we find it is also a singing part. And he can also sing apparently. That could have been a trainwreck for a compulsively shy and scared scatterbrain but he somehow pulls it off. I think that was the moment where I checked out.
Or pushing the car to the dam to see the sunset, like why? How long did they do that? How were they physically able to do that?
