The dumbest (of many) things about the suicide plan at the end is that the whole point of the main character is not to become like them. He proves that in a stupid way in the Russian roulette already. But somehow he thinks it's ok to sacrifice the whole team of Xs? It would have actually been more moral here to kill the Os, so you can at least try to save those Xs.
Length of the season... I legitimately thought this was only half and they would drop some more episodes soon. But I guess that will be season 3 then?
Characters... The mom was really cool. God damn it was heartbreaking to see her and her son and also how they hung out with their whole gang including the badass transgender girl. I don't want them to die in season 3. These were the insane emotional moments I thought I remembered from season 1 and which really make the show. When they played this carneval doors game and they got split apart... uff.
I also agree the guy whose boss got killed is cool and the recruiter at the beginning was a sight to behold.
The show also always has some minor annoyanes that are easier to forget. For instance, when they only have 5 minutes to finish a game, they keep wasting several seconds to celebrate or get mad? I know people are stupid and in such a crazy setting you would also sometimes behave stupidly, but that still seems insane to me.
