Well, this is what happens when I don't plan ahead.
You see, last week's theme was Summer Vacation, and I picked a lovely little movie called The Way Way Back, which involves a boy and his mother going on vacation to the mom's new boyfriend's beach house, and the boy finding a job and family of misfits at the local water park.
And then I see that this week's theme is Amusement Parks.
Clearly, I should have thought about this a bit more.
Anyway, now I have to stretch the definition of Amusement Parks a bit in order to get three, but I don't think there will be too many complaints...
