One of the few feature length films legendary cartoon director Fleischer helmed. Mr. Bug Goes to Town is a pretty decent and capable alternative to the Disney School of animation, though it's not quite distinctive enough to really set itself apart from the mousy shadow that looms over it at all times.
The story is extremely basic. Hoppity needs to save the inhabitants of Bugsville when their little piece of heaven is on the verge of being destroyed by a giant skyscraper. How exactly that leads to bugs singing is still a bit of a mystery, but it's safe to say that the plot isn't carrying too many surprises.
The animation is decent and some of the character designs are pretty nice, but the film's a bit loud, some of the characters are plain obnoxious and the songs have no added value whatsoever. It's still a pretty standard children's animation that may have some technical chops, but doesn't accomplish much beyond that.
