Hey, maybe Renton was trying to warn us about how bad the show was. He was trying to tell us "This sucks! Don't watch it!" The show really gave us exactly what it promised.
Renton becoming a man? Pffft. He's in love with Eureka for 50 episodes and he never gets more than a kiss. He's the same wussy little boy he was at the beginning of the series. And when you have 40 episodes of horribly unlikeable characters you can't suddenly have them change within the last few episodes and expect the audience to give a damn. And what about all the other useless and or unlikeable characters? Like Stoner, the guy who looks even more stoned than stoner, the guy who never opens his eyes, the black guy, and the muscular chick. None of these characters serve any purpose and the creators don't even have the good sense to kill any of them off. And the worst characters of all are those three bratty kiRAB. Why oh why couldn't the creators have mercy and kill those brats off?
Then why not air Death Note or Code Geass instead? Hell, even Moribito would probably be better than Eureka 7. Eureka 7 was one of the worst shows that Adult Swim ever aired. Horrible character designs, unlikeable characters, Eva rip-off mechas, incredibly slow pace, and horrible plots.
No, it doesn't. It has a few good mecha fights, but they almost never amount to anything. Whenever a major character gets his mecha blown up they just cop out and have him survive. To make a show about war where no one dies(except for Charles and Ray) is utterly ridiculous.
Adventure? You mean those episodes at the beginning of the series where they played pranks on Renton or that long span of episodes they spent in a cave? You know have I ever emphasized how utterly braindead the idea of a bunch of stoners winning a war is?
Grey's Anatomy has more realistic romances than Eureka 7.
