surprisingly bad, unfortunately
this wasn't a good idea for a flash. you've taken a video that either doesnt exhist or exhists in some random nerd's copied video closet and made a parody of it. the animation was ok, but there was no storyline, or no egoraptor-esque comedy. top that, the voice sounded like some extremely ill or high colege student. then, you made it so long that any comedy aspect or value in watching was lost. who the heck are these people, and why, why are their ~7 guys randomely popping up in full body paint?!?
you said it best yourself-
"Deep in the cockles of some lonely thrift store lies a classic gem so horrible only the few great collectors have ever laid eyes on it."
here's where you could improove
1. parody something more main-stream. i mean this is too rare of a movie to parody. i havent seen it-ever. it would have been better if you either did something completely original with your own charachters, scenes, and influences.
2. the voice syncing was HORRIBLE!!! you're a flash ARTIST!!! not AverageNewgrounder or some spam artist. you should be doing this well.
3. the main charachters should not look like they came out of a chinese "karaoke" club. i mean, honestly, this is a new low when a charachter looks like a hooker. there, i said it, hooker.
4. kill the redundancies. i could only STAND to watch this for 3 minutes, and i would not be surprised if half or the text contained an abnormally idiotic name for a person or mountain like shinkenbatsuhatsu...WHY AM I GETTING SO FAR OFF TOPIC! (sigh). also the stupid references to brothers or sons or whatever. not funny.
5. everything was random. so completely random. a storyline would be nice
6. the voice acting was horrible. some exerpts may help
"uuh"
"uauuh"
"uuuauah"
it sounded like you took one take for some reason on voice acting. BIG no-no when the acting kinda sucks i mean, i would have given you at least a 6 if there was some crappy piano music and pop-up subtitles like some old-time silent movie, but the audio sucked.
i honestly dont know why this is being rated so high, maybe people see the name and say "egoraptor=10 and 5 review and score". but really, this needs to be fixed.
