Characters. S1 had lots of them, but next to no personality or development for anyone. S2 rolls in and offers several personal arcs, but executes them horribly: excluding the girl that has recent events that weight her mind, the rest of the crew in their respective arcs suddenly get a personal problem that came out of thin air with no build up, spew generic empty words for half an episode, have one fight - and their problem is now completely solved while the character in question got a power-up. It feels extremely cheap and causes nothing but irritation.
World/monsters. The same problems as S1 - somehow a society that has been living under a constant kaiju threat is completely unprepared for assaults, enemies pop up without a single warning but humanity refuses to learn the lesson or do something about it. As for kaijus - again, the strongest is just some dude in an animator suit, and if you came into an anime named Kaiju expecting kaijus - well, jokes on you, even when present they are just big targets, not an enemy anyone cares about.
Fights. We are constantly shown lots of low-ranked guys doing zero damage while waiting for a named character to show up and oneshot the target. Is it fun? No, it is not. And it is even less fun to get a cliffhanger ending of the season in the middle of the final fight. Sure, you want to sell a movie for further profits, but what the hell man, have at least some decency. Overall - there are no memorable fights, because they are saved for the last season/movie, the fights that we got are extremely lame.
Plot. Still predictable with obvious development and no sudden turns. Sure, it is functional, but it is boring to watch.
Overall: S2 is a continuation of S1, but instead of developing whatever good things it had it just stagnates. It was boring to watch and the abrupt ending feels like an insult.
