Just watched episode 1 of Aim for the Top 2. What a load of crap. The animation was excellent, even if the chara and mecha designs sucked. It definitely looks like FLCL all over again. Not just in terms of design, but style as well. It's a lot more cartoonish than the original, that's for sure. They're definitely going for action/comedy, rather than the blend of drama, comedy and action that you'd expect from Gunbuster (nothing like the heart rending opening monologue in the original here). It also felt like there was very little tying it to the original, which might be a good thing. Even if they had made this show completely separate from the Gunbuster setting, it still wouldn't have been that great.
*SPOILERS*
What the hell?! Fine, the characters are psychics, but taking out a space monster with your bare hands in orbit without a space suit? Yeah, I realize it's just a show, but my suspension of disbelief was shot to hell. And yes, the original show had fan service, but having a character rip her shirt off in the middle of a fight for no apparent reason is just beyond gratuitous.
