Goseiger is alright, but it messes up a lot. Power distribution is all over the place (Multiple episodes in a row of gaining new abilities, and episodes that centered on one character featured another character getting new headders for no reason). The villains are rather dull (Warstar is basically Sentai default: Evil king sitting in dread fortress doing nothing, the mutant things are even more dull (Their arc just drags on and on), and the Mantorintis are a total afterthought with how little they ever get to do (They're basically used to set up Brajira and his heartless nature, rather than be real adversaries to the Goseigers). The characters go from happy go lucky to complete idiots (I can understand Eri putting her all into making a boy have a good birthday. I can't justify her abandoning her team to bake a cake), and GoseiKnight, while my favorite character, doesn't really bring anything new (Sixth with a chip on his shoulder that shuns the team and thinks they're bitches). His story arc of understanding humanity with...Nozomu (Was that his name?) was quite nice, though.

With Goseiger, the first third it too stuffed, the second is just a slog, and the 3rd, while nice, means you've already spent 30ish episodes to get to.
