identity

http://www.imdb.com/title/tt0309698

identity was not formulaic, but it was only mildly suspenseful, and the characters were not that interesting.  the ending was fairly obvious well before it arrived, though it seemed to me that the killer could have been anybody, including one of the people who had already died.  it was that kind of movie.

i give this one two identities.  GUESS WHICH ONE IS THE KILLER.
