I did not the enjoy the movie so much, Luca Guadagnino's one.  Why? Just because I don't understand why he took my movie. It's not a remake.

Dario Argento's Suspiria (1977) is a classic. There's simply no other way to describe it. Its use of garishly bright color, the amazing soundtrack by Argento's band Goblin, and Daria Nicoldi (Argento's wife at the time)'s fairy-tale-inspired story are groundbreaking.
