Argento's most underrated film
I thought this film had an interesting premise, good acting, good atmosphere, good music, etc. The twist was very well done and there's even a cameo from the great Brad Dourif.
This movie made me fall in love with Asia Argento. She's so great as a damaged teenager, I wanted to take her in and take care of her myself. It was also a fearless performance for her age.
Overall it's a great mystery, and the only flaws are that the deaths get a little repetitive, there's a couple plot holes, and one death that I think was supposed to pay homage to VERTIGO didn't come out very well.
