We took the children out to the movies today. We saw The Pirates Who Don't Do Anything.
It reminded me of Galaxy Quest - similar plot, a couple similar plot tools. It was cute. There were a couple jokes that you just had to laugh at, and more than a few spots to grin. I wouldn't say it was a classic of American filmmaking, but I do think it was entertaining, and worth the expense for the kids.
It was a bit talky for a kids movie, but it was cute enough. Even the Apple sat still through it.
All in all, I'd say it's decent matinee fare for a child between 3 and 6.
