Corrected entry: The whole film doesn't work - no-one in the film could possibly be the killer. At the times of the murders all the cast are accounted for.
Corrected entry: In the film the four friends figured out who the killer was because of his link to the mask that Kate found in her elevator. I wonder how they came to this conclusion as at the beginning of the film it is not Jeremy Melton who is wearing the mask, it is a child watching him.
Corrected entry: When Lily is shot with all of the arrows and falls into the dumpster, why doesn't anybody discover her body throughout the rest of the film? Wouldn't somebody notice her body when emptying or adding garbage to the dumpster? The dumpster was full of garbage, meaning that it is frequently used.
Corrected entry: At the end of the move when Kate is running around the mansion, where did all the party staff go? Would someone as wealthy as the family is supposed to be just leave their house trashed like that?
Corrected entry: Why is Lily watching dating tapes when she has a boyfriend? And also if you looked like that, then you wouldn't need to watch dating tapes, men would be falling all over you already.
Corrected entry: In the scene where Lily is being shot with arrows when the killer is firing the first two arrows his nose is already bleeding. However, when he fires the third arrow his mask is clean, his nose is not bleeding and his nose only starts to bleed again when he pulls back the string on the bow.
Corrected entry: In the scene where the killer is after Shelly she stabs him with the scalpel she was using then drops it. As she is running and presses the lift button there is no scalpel in her hand but when she resumes running away the scalpel is back in her hand.
