It was amusing to see the droves of adults who went to see "What Lies Beneath" because of the stars. "What Lies Beneath" is basically lite-horror fare, a "I Know What You Did Last Summer" targeted to adults.All jokes aside, it was a nicely done thriller without the help of a knife/hook wielding serial killer with a cache of bodies hidden in the basement/tower/freezer. A lot of critics griped about some of the standard devices used to frighten the audience. Well, in my case, it still worked, so if it ain't broke... I jumped out of my seat a few times. Overall, a nice psychological element to all the terror rather than relying on the ever popular gore. Both Harrison and Michelle did a nice job on their characters, which makes up for the few slow moments in this movie.
