Interesting movie. What puzzles me was that I thought she will finally realize she was dead and pass on, but I saw her fighting to get out of the casket after she was buried...
She broke all her finger nails in doing that, and after she was 'uncover' and taking out of the casket by the boyfriend, she still show the broken nails...though, may be that did not happened at all? Liam say that the boyfriend never made it to the cemetery......he got kill before that. Weird movie, I think I will watch it again to see if I can discover a new angle to it.
