Gunbuster:- Has good art, strong story, bouncy titties & mecha designs that I like. Win.
Macross:- Has strong story, mecha designs that I like, but inconsistent art and no bouncy titties. Ambivalence.
Macross Plus:- Has mecha designs that I like, consistent art, has titties but no bounce with half-baked story*. Ambivalence.
Gurren Lagann:- Has good art, strong story, bouncy titties & mecha designs that I like. Also has GAR. Sure Win.
So, if I have to pick only one anime that I like so far, that would be Tengen Toppa Gurren Lagann.
*Half-baked story because I don't buy into the crap that a person, even for an alien half breed or sumting... can block out a bad memory that happened as recent as 7 years ago... especially if I saw the pair of titties of the girl I like for the first time. Yeah maybe my memory could be hazy abit, but it's still a hazy looking titty. And that I, as a third person viewer, was not allowed to look at that pair of titties, when the protagonist is looking at them, is a nail in that anime's coffin. Nuff said.
