Generally I think of the visuals and gorgous lighting and colours first with Suspira, the music second and then the voice dubbing and surreal acting kind of clouds things over from then on. Even the plot is more tailored around showing the viewier with the (at the time) goriest and most disburing deaths than actually being coherent. Though I will say the movie poster is probably one of the best around for horror.
Somehow normal rules do not apply. Part of me blanches at such a beautiful giddy experience being made from the fictional murders of young women, while another part of me is just enraptured by the colours, colours, colours - it's probably that tension which makes the film so very memorable. Too spoopy for giallo.
Suspiria is one of the most unique audiovisual experiences I've had with a film. The way Argento and his cinematographer combine the intense RGB lighting, with an ear-piercing, almost avant-garde soundtrack, absolutely floored me. They create such an unsettling feeling, that even when the content behind this psychedelic curtain is delving into very corny territory, the film maintains almost all of its intended mood.
There isn't exactly a lot of attention to plot, and I'm always skeptical when a horror film relies on shock-gore. But then there's the total craft: the acid colors; the irresistibly demented sets; the Goblin score played as either warning or tease; the editing that synthesizes all the above; and Jessica Harper as the perfect wide-eyed lamb. Curious about the remake—there are ways to fill in this spook story's holes.
I can't for the life of me understand why this is the one that's remembered out of Argento's stuff. Probably has something to do with it's vibrant visual flair. Personally I prefer 'Profondo Rosso' to this, to me it managed to produce a better balance between style and actual substance.
