Hey, I have kids, but my wife and I enjoyed this as well. Banderas and Hayak voiced the hell out of this. There are "hidden" adult jokes here and there to appreciate even as they go over the kids' heads. The animation is great though you can tell the many roller-coaster-like sequences are there to exploit the 3-d, and feel tacked-on and an unimaginative use of the z axis. That's pretty much the only fault Icould find with this movie.
Banderas really is funny in this, lampooning the roles he so often gets cast for, I have to say he's a very good sport.
