The boys, being boys, wanted to see it. After doing some research on it (because it is PG-13), we decided that they could watch it. I don't remember any profanity. There were no sexual scenes or innuendos. It was just heroes fighting bad guys and heroes fighting each other for dominance. That is it.
Once school was out, the boys and I walked down to the local theater to get the movie tickets for the showing later that night. If you have been to our town, you might recall that the movie theater is on the opposite side of town from us, probably a few miles. Nevertheless, we walked over to it, bought our tickets and walked back home with a detour at the playground. We were gone for two hours, but it was two hours well spent.
