That movie was a great example of what a cheesy concept for a scifi/thriller movie should be when done right.
Here's my only issue: I watched it with my dad, who was just a great guy but a self-avowed "dirty old man." The comments that he made during the movie were... well, off-putting. I was trying to engage in my willing suspension of disbelief, and he was commenting on the charms of Ms. Kinski and what was being done to her. I mean, damn, Dad. Come on. The movie is more than looking at some bits.
This is TMI, right? That's what this site does to me.
