Never seen any of these movies,they any good?

Not as good as the first, such is the case with most sequels.

What ever happened to Some Dogs Go To Hell? Starring Old Yeller, Benji and Cujo?

I used to have this on tape!

I love this movie! I think it's just as good as the first one.

I didn't care much for the sequel. But I loved the music.

Not as good as the first one. I'll just leave it at that.
