The latest movie that I purchased as The Covenant. Even though it was released a year ago, I never actually watch it. It looked like it was really awesome, and it was. It was well worth my ten dollars.
The latest movie my father purchased for the family was Tinker Bell, though that seems to be more for my sister than the family.. but regardless. I saw some clips of it and it seemed to be a really nice movie with a childish yet not so childish plot.
If this includes going out to see a movie (since, well, that could be the same thing because you're buying your way into the theater), it would be High School Musical 3. Best movie I've seen in theaters since Harry Potter and the Order of the Phoenix.
