In this review I will touch on the difference between this season and season 1 of the show.
Basically... this season is a lot better for a few reasons:
MC is barely in it and boy does he suck.
The characters featured are far more sympathetic and relatable and make the story far better (they are lots of characters whose names I know from history so I can relate on several levels).
You can see the story is building up to something and it all makes a LOT more sense.
More cool fighting scenes and several romance plots that were done well/
The things that are still lacking to keep this from being more than just good:
MC still sucks.
The more I find out about Horizon the less I like her. Could she show a little emotion?
There are less logical debates which I really enjoyed.
The story stops after introducing a lot of new potential characters; they didn't want to end it they clearly got canceled.
Even more characters gain special powers because they need them to win battles.
Overall: better than season 1 and I suggest definitely watching it if you've seen season 2. Not sure it is worth going to the source material for the whole story though I can see the beginnings of an epic story unfolding that some may want to explore.
