Just caught this on Acorn, after it's already 11 years old! Very suspenseful, definitely has you guessing and convinced you know who it is but then second guessing yourself again! Even the ending was good, even though I see many reviewers wanted it to end differently, I thought it was a clever twist. Only thing that bugged me throughout was the main female character. She was a horrible actor. Had a bland, dour expression on her face no matter what she was doing. The brief times she smiled it was like the director had to remind her, ok, you're supposed to laugh or smile now, don't forget! I kept wanting for SOME other character to ask her why she's so emotionless!
