I thought the acting was great including Katherine Heigl. The only other movie I ever saw her was Bride of Chucky, which I thought she did great in too. I never saw any other movies of hers, although I know a lot of people don't think she's a good actress. This movie is nothing original, but I like it just the way it is. Enjoyable edge of the seat thriller for me. Don't always pay attention to the ratings on IMDb. Sometimes it's better to just see it for yourself.
