My favorite among Argento's Giallo films!
13 April 2004 | by (Germany) – See all my reviews

First of all, I am in fact a big fan of Dario Argento and his work as a director. I always liked his suspense thrillers more than his almost pure horror films. I love films that content a good and well-structured crime story with a lot of suspense. The Italian "Giallo" is therefore one of my favorite genres. I already saw Agentos early "Giallos" like "The Bird With The Crystal Plumage" or "The Cat O' Nine Tails", but honestly I have to say that "Sleepless" became my favorite one among his "Giallo" films. And in my opinion "Sleepless" is a good "Giallo", may be a new kind of "Giallo", but it still has this certain mystic atmosphere. The music from Goblin who also contributed the Soundtrack to "Suspiria" is excellent and fits very well. The camera work is classic. The only point that lacks a bit like in many other Argento films are the actors. Max von Sydow is real great in this role as the retired policeman, but especially the younger actors cannot cope with such a performance...

As a result, "Sleepless" is a real good and entertaining murder mystery with a lot of suspense. It was obviously the right time for Argento to take a step back and do another "Giallo"!

9/10 points!
