I'll have what the twelve year old is having.

[Lace Neil Singer]

Heavy Metal
Fritz The Cat
Cool World
Who Framed Roger Rabbit
At least half the films shown at Reg Hart's Sex And Violence Film Festival

Just because it's animated doesn't mean it's suitable for kids.

Adding to the list:

Watership Down
Plague Dogs
Felidae
Most anime, special mention Elfen Lied where the first five minutes has nothing but people getting ripped apart!

I don't think that kids ever belong in bars. I don't care if you think your kid is the most mature ten year old in existance, do not bring them to a bar. They will be bored to tears and their presence will cramp everyone else's style. Luckily, round my way all the bars don't allow under eighteens, tho some idiots do try to get their kids in, they are soon shown the exit.
