I didn't think this was funny - even if it was a trailer, I don't think the thing it's advertising is going to be funny. The animation could of been alot smoother, when the text was shown, you could of made it fade in and out and keep it there for a longer amount of time so we can actually read it.
Please, just put a bit more work into your flashes. If you can't at the moment, then practice. You'll get good unless if you're just doing this for the flash count +1, then that's quite silly.
Well, I have my fingers crossed hoping you'll make a decent flash someday. But for now, if you keep submitting stuff like this, it really only just deserves a 0/10. Sorry.
