Brilliant. Why didn't I watch this sooner?
Even though I'm on newgrounds often, I didn't watch this movie until today and it was only because the theme song was topping the audio portal!
One needn't to have seen the movie or read the comic to realise that the characters are protrayed in the opposite manner than they really are. I need to remember that when I go see the film and read the graphic novel. I'll probably end up laughing inappriately in the cinema over this when I'm watching the film!
Anyway, back to the flash. The animation was simply brilliant, really captured the 80 cartoon vibe right down to a tee. A lot of people on youtube thought it was real ( nice touch with the video icons on the screen in the youtube video ) and who would blame them, its a perfect imitation of the 80s cartoon style, even though they were a bit corny, those days that are now sadly missed.
I though the way you put in the credits was good as well, just like the title card of an 80s cartoon, another excellent touch. Hell, it had me fooled at first as well, I thought they'd be an episode as well!
All in all, excellent work.
