Impressive graphics...
I liked the graphics, they were nie and smooth - and the animation was pretty good too - although more could have gone on in the movie. I like the closeups of the character's faces though.
A little short, but yes I know I know - a trailer. I just think that you should have not released this until the real thing comes out, beacuse it's like you've used material here taht you could have integrated into the main movie - if you do that now it'll kind of cheapen it a bit...
I liked the batman idea too, hehehe! Oh yeah - and your main menu sucks - you need to make it clearer and bolder, with the title of the movie more pronounced, but that's not really too much of a problem.
Basically I'd like to see much of the same thing in the new movie, but with more "action", and I don't mean violence necessarily, just more action-shots, more panning, zooming, etc - and obviously more jokes. Plus the voice actors aren't the best - but it's damn hard to find 'em anyway as I'm well aware, trying to find some for myself!!
Take care and good luck with the project
