The characters are less credible than their plastic counterparts, the puerile humour is dispiriting, and the plotting pulled this way and that by the conceit of releasing the film in the US with a trio of alternate endings.
Only Lesley Ann Warren, as a tough-talking madam, finds an effective level of stylization, using her leggy physique and wildly expressive features to create a cartoonish figure that's funny within its own boundaries.
It's not the least bit scary or suspenseful but instead quickly grows tedious. The more you struggle to keep track of the constantly multiplying plot developments, the harder it gets to care who did it.
