We saw it too! DS almost 5 was totally absorbed in the movie but afterward said it was just okay.
When I exchanged the vouchers for real tickets the attendant asked me if I wanted to use all 4. I said, well, DD is only 2. They just took 3 and told me I could use the other for any movie (just take the sticker off). I don't know if I will feel comfortable using it for another movie, but I thought that was really nice.
