I like boy-meets-girl space themes with action and decent graphics, with slinky gals, occasional jiggling, people who aren't [bad], and this has them. I prefer anime where the genders mix and goofs happen and comedy occurs and sometimes there is heart break. The plot and story aren't necessarily new: Martian Successor Nadesico and a few other series have similar plot. There are pirates, transforming mecha, battles, glitzy affects, and so on just like others. But, it is told with enough original details to make it fresh (beleive me, I have watched a lot of shows, and a lot are pretty dull, so I won't say that without need).
Perfect? No. I am also looking for mature (not twisted nor peverted, just mature) themed anime along the lines of boy-and-girl-have-already-met-and-married-and-have-kiddies to get out of the kiddies in high-school level most are, but since most anime is intended for young kids and serial TV showing, I don't really complain that I don't find it. Series like these make the wait okay.
Nudity? Hmm, gotta look harder I guess. Haven't seen any real nudity in it. Maybe some of the reviewers haven't seen the show? (Or maybe they think of nudity as something other than really naked people?)
