Mirrors (2008). Starring Jack Bauer, George Romero's Bruiser and the butt of Amy Smart from the Crank series!
A lot of people have said that they have a problem with the way this film ends. Not me, though... I thought it was neat!
Now I just wish that the thing had earned enough money to warrant a sequel. Oh well... I guess that's what my imagination is for!
EDIT: Yes, I am aware of the since-released direct-to-DVD sequel - but considering that it has about as much to do with the first film as Amityville Dollhouse had to do with its parent series? Well, somehow I think that I'll give it a miss.
