Any attempt to re-create a 1970's giallo in 2003 (after the once great Italian exolitation film industry had gone pretty much belly-up) was probably somewhat doomed to failure. This isn't a total failure, however. It is certainly better than the last major attempt to revive the giallo (1996's "Fatal Frames"), and even better than some of Dario Argento's latter-day efforts (it's better than "The Card Player" if worse than "Sleepless" and "Do You Like Hitchcock?"). A sexy young teacher is killed in a high-rise apartment building using an architect's triangle. Not only aren't the other tenants too disturbed by it (as in the deliciously absurd 70's giallo "Case of the Bloody Irises", they even use it as an occasion for practical jokes), but several of them hit on the idea of committing copycat murders--to get rid of black-mailing maids, unfaithful lesbian girlfriends, etc. Naturally, this leaves the police, and the female detective who is the lead investigator, baffled. Unfortunately, it also creates a situation where the viewer knows more than the protagonist and is waiting around impatiently for her to catch up. The movie then tries to make up for this by going in the exact opposite direction with an infuriatingly ambiguous ending. Thus an initially clever plot is decidedly fumbled.
The style is OK albeit slavishly copied from earlier, better gialli. The movie does feature some of the old familiar giallo actors including Franco "The Fifth Cord" Nero, Florinda "A Woman in Lizard's Skin" Bolkan, and Eva "Tenebre" Robbins. Bolkan is pretty good as violence-obsessed painter, as is Robbins as a lesbian actress given to walking her cat(!)around on a leash. Nero is more wasted as a former detective turned ranting street preacher/prophet. The biggest problem though is the godawful English dubbing (none of the actors dubs his or her own voice even though Nero at least, is perfectly fluent in English). It's not that gialli have ever been famous for their sophisticated dialogue or naturalistic acting style, but NO movie deserves this kind of sh*tty dubbing job.
Intentionally or not, the gory special effects are up to about the 1970's level and seem pretty laughable by today's standards. They do get the nudity level right at least--this is not a tame Hollywood thriller aimed at suburban teenagers where you don't get anything more than under-dressed (and underaged) American TV idols, but neither is it an "erotic thriller" where slow-motion softcore sex scenes by silicone-enhanced "actresses" bring everything to a complete stand-still every five minutes. Not that there's no silicone or surgical enhancement on display--the most attractive actress seen in the altogether here was actually born a man! (See if you can guess which one). This is also not to say that I would necessarily recommend this, especially to non-giallo completists, but it's not THAT bad.
