Thanks, I did! My memory is sketchy but wasn't there a lot more in the book about the rats being at NIMH and getting smart and stuff? That was the most interesting part. I enjoyed the animation more than the movie itself, but I'll give it 6/10.

Watching it reminded me of another animated movie I saw at roughly the same age - Watership Down. That was one of the most intense animated stories I've seen (that is regarded as suitable for children), though that Bright Eyes song has always annoyed me.
