Argento's first directorial effort is compared with Hitchcock, but as tempting as that is, Argento is compared with no one. He has his own style and that style was displayed in his first effort.
What seems like a straightforward slasher pic, is far from it.
There are clues throughout, even though they don't look like clues when you see them. One finds it strange that the protagonist (Tony Musante) follows a lead that doesn't make sense, and a clue is revealed that doesn't help us either.
Why is everything so muddled? Because this will end with a surprise, and then everything will make sense. So, don't try to guess, just enjoy a great Giallo and wait for the Hitchcockian surprise.
