Taking every staple of serial killer thrillers and hard-boiled detective films, Argento constructs the most hackneyed and clichéd film possible, filling his cast's mouths with some of the most hilariously awful, clunky and absurd dialogue imaginable. Brody and Seigner play the entire thing 100% straight and you imagine there must be one hell of an out-takes reel somewhere. From Brody's perpetual smoking and eternal frown to Seigner's crazed histrionics there's a sly gag going on here.

The problem if there is one is that so much of Argento's recent work has been genuinely terrible, that there's a nagging doubt as to how much of a parody he intended this to be. With the line between homage and parody blurry at the best of times, Giallo has understandably met with some mixed responses. Taken as simply an Argento horror film, and you'll quite rightly dismiss it as another gross misfire and reason to give up on the old fella forever. Take it as an incredibly sly parody (the heavily made-up killer is credited as Byron Deidra, an anagram of Adrien Brody...) and you'll most likely find much to enjoy. Whereas previous Argento failures have been just plain bad in terms of plot, dialogue or character, Giallo goes beyond this to meticulously pick up on the overused conventions of the genre and its typical script deficiencies. Affectionately highlighting the absurdities of these genre pieces, it's very much (I hope) a self-referential in-joke.

Some of the famous Argento touches are still there, particularly in the trademark close-ups of knives bloodily piercing (latex) flesh and the eerie childhood flashbacks, but of course taken on parodic terms these become comical rather than scary or horrific. What it does make you sadly wonder is whether we'll ever see the director do a proper horror film again, but arguably that possibility was scuppered sometime in the late 80s. Either way I can thoroughly recommend this as one of the most purely entertaining films of recent years.
