Story - 7
Up through the first major arc, the story was alright, made sense, but during the second major arc, the story started making less and less sense. I can put my disbelief on hold to an extent, but you'd have to really be able to do it to buy all the things they try to tell you. Also, I don't buy the ending, not just because of the obvious thing if you've watched it, though that is one of the reasons. I could go into a long rant about it but this isn't the place for it.
Art - 8
I don't really have much to say on this category, it wasn't bad, but didn't wow me. It was very colorful though.
Sound - 6
This is where Gurren Lagann suffered to me. Very few tracks stood out to me, and I didn't get as pumped by the OST as other animes.
Character - 8
Well, the characters were all pretty straight forward, I would say Simon's really the only one with evident character growth. Kamina annoyed the hell out of me. Yoko's kind of the poster girl with a large rifle and loses purpose other than eye candy later on.
Enjoyment - 9
The show moved at a fairly rigorous pace so it kept the enjoyment factor up. The show's all about the indomitable human spirit, and that messages resonates with a lot of viewers.
Overall - 8
I don't think I can give the show higher than an 8. I honestly don't know why this show is so highly rated relative to other shows I've seen that I would rate equally or higher. Don't get me wrong, I enjoyed watching it and it's not a bad show, but there were just too many things that bugged me about it.
