That's what ruins the show for you? REALLY?!?
Get the fuck over it, man. Plenty of other minor nitpicks with the new series, but to be so hung up on one of the few female characters not having a matching body? Are...are you a nerdy 14 year old, now?
FWIW, I loved the original anime series and movie, and I also enjoyed this new live-action. It was obvious they tried to emulate the original stylization and cinematography, copied/recreated the intro, etc. I liked that they kept the original theme song.
There were some small issues I noticed here and there, but this was likely one of the best animation-to-live action adaptations that I've seen.
I already liked John Cho, but I thought he worked pretty well as Spike.
