In Czech Republic, we have an annual Festival of a hardened viewer. Lots of old great movies with simultaneous translation in the headphones. Awesome, I saw Basket Case last year and laughed my ass off.
The one time I saw SUSPIRIA in a theater it was terrible...the print was ragged as hell. I guess some people probably like the "seediness" of that, or the old timey feel, but it's a serious film that should be viewed in the best possible circumstances in order to fully appreciate the cinematography, sound, and color.
Either way, looks like I won't be seeing it...turns I have to attend a wedding the following morning (doh).
