Tom Goes to the Mayor is complete garbage. The gags are completely killed by the asstastic voice acting. It's like if you took the Simpsons, then fired Dan Castenella (sp) and replaced him with a teenage stoner. But still have him do all the characters Dan does.
The shitty looking character photoshops don't help, either. There's nothing to identify with other than a bunch of random faces. Hell, the "Spirit of Xmas" South Park short has better animation! Oh, and it's actually funny.
Can't comment on VB, haven't seen it.
