Even though I don't really care for Jim Carrey, the movie was very good. Not meant for little kids, though. Had some scary moments. Much better than I expected.
I saw this one today, I thought the same, there were a lot of kids in the theater for this showing.
I am hoping when release this one they release a directors cut, even tho I like this film I was left with a fealing that there was much much more that got left on the cutting room floor.
