Regarded as one of Argento's lesser works, I find this one much more plausible than any of his early films. Let's face it, Argento doesn't care much about plot or even acting. His films are probably the frustrating I've ever seen: There are things I love, and things I hate about them. I grew up watching much of his films mutilated by Italian Television. I was a kid back then, and strangely enough his films never scared me when they were supposed to. They were really over the top. But I loved the colours, the pictures and once in a while I found myself humming Claudio Simonetti's electronic scores.
Now with this film Argento has Morricone, who is definitely a master and he does a great job here. Anna's character is really intriguing. Some people dismiss Asia's acting style, but I think it goes very well with her father's aesthetics. You wont find the crazy colours here. Everything is more restrained. The opening for example scene is great. But the film looses interest towards the end. Still I think is one of Argento's most solid pieces. The idea is truly interesting and Anna's relationship with the killer is fascinating. The hallucinations scenes of Anna going into the paintings are masterfully done.
After the huge disappointment of Il Cartaio, I hope he truly returns to form, and start doing what he's good at: Going crazy with film. La Sindrome Di Stendhal is a pretty good step.
