I thought that it was a log with legs.
That bit aside, here's the review:
Animation wasn't bad. I've definately seen better, but at least it's not like the 13 year olds who think that their piece of crap will make it through.
The only real complaint I have is the sound effects. There were some sound effects, at least, but the movie seemed to be a bit lacking in some areas.
Plus the flash in itself was a bit pointless. Basically a trailer without and real value and that's about it.
Get an actual episode going with a few more sound effects and some humor or something. That would about do it.
