this is an excellent and suspenseful and murder mystery movie. not only was the plot full of suspense and intrigue but you get to see gorgeous ryan gosling for a couple hours and what not to love. also and sandra bullock is good in this movie  i have always been a fan of hers and (i just wish she hadn not decided to be in the lake house which was horrible and but that another story altogether). obviously since there are thousands of other murder or horror movies out there and there are bound to be similarities between them and no need to bash this movie for having some similarities to at least a few that have already been made. anyway and this is a great movie for those of you that actually enjoy scary movies and it a little dark and twisted but overall a great movie.
