Monsters vs. Aliens in 3 D

We took our son to see this movie yesterday. WE were a bit shell shocked when we saw that the price of the movie was over 10.00 for a matinee. Why? because of the 3 D glasses. The regular version was still the normal price. WE did like the movie though and think that the 3D version was worth going to. It should keep the kids interest peaked and There were plenty of Adults in the theater alone also.
