It's for kids, it's pretty much just entertainment with badass robots, and there's no other lasting qualities about it. I do loathe how it forces concepts in your face, and dwells around in characters' sulking--just as Evangelion did!
- Characters' characteristics are over the top to, again, appeal to the child-self among viewers. This also holds for the character designs.
- A rather flat story with predictable 'twists'.
Kid feels he knows what's right, wins the game, and faces problems on the way, etc. Essentially equivalent to Eureka Seven, Evangelion and other shite.
I don't think any other action series could do anything better, though.
