Hahaha. Mostly, I'm not a fan of the Horror genre. However, I did see Sssssss way back in the 1970s. I remember being vaguely creeped out, and mildly titillated; I had a closeted gay teen crush on Dirk Benedict at the time, so it satisfied that urge. Looking back, it was a pretty silly and absurd movie. I'm pretty sure I'd laugh my ass off watching it now as an older adult. But you're right, the makeup and transformation were pretty remarkable for its time. I'm sure they'd just CGI the whole thing now.
