I'm a big fan of the games and I couldn't make it past the 2nd episode.
Great at fan service and production, terrible on plot and dialogue. Misses the tone of the game, satirical with heavier themes, and instead has the mood of a children's action show but with hyper violence. Fights are cheesy, characters are goody without being interesting or deep, humour is "random" or silly but not clever at all. It feels more like Borderlands.
