An older review for you (not that reviewers matter in many cases, since most of them are full of shit, but this was right on the money)
On your beloved Suspiria:
"a horror movie that is a horror of a movie, where no one or nothing makes sense: not one plot element, psychological reaction, minor character, piece of dialogue, or ambience." --
New York magazine's then film critic

If ketchup and tomato soup blood does it for you..
To me, this isnt horror, this is teenage kid crap. But listen, I won't deny Suspiria was an original flick. Having made no sense, and full of weird imagery, it tried to be something different. And IMO was still a failure. But to each his own. This kind of kiddie stuff just doesnt do it for me.
