Worse than Salo?
I watched Ilsa many (over 10) years ago when I was in my early 20's and was deeply disturbed by it. For this reason, I hesitated in viewing Salo until only about 6 months ago. I was surprised not only by how good Salo was, but how much more disturbing and shocking I found Ilsa. Salo has a few nasty scenes, to be sure, but Ilsa is just unrelenting.
I understand that the scenes with Ilsa and her male conquests are intended for camp effect, but the fact that they were intercut with scenes of horribly brutal torture really left a bad taste in my mouth. This is an ugly, ugly movie that left me feeling like I needed a shower afterwards.
In contrast, Salo actually has something meaningful to say with its scenes of depravity, and so I wasn't as disturbed (though I was grossed out at times).
I don't understand how some of the posters on here can refer to this movie as "fun". What's fun about it? Women being boiled alive and deliberately infected with syphilis is "fun"? Hostel is fun. Dead Alive (Braindead) is fun. Even The Devil's Rejects is "fun" compared to this. But this...this is one sadistic film, and it has no point other than to be sick and sadistic.
