only good thing was the sex scene

I agree!

Although I liked the movie overall more than you did, I agree that Lowe's bedroom scenes with both Cattrall and Tilly were tres hot. I thought Tilly really sold that scene -- to the point that i had to wonder if they weren't actually having sex on camera! It was a great example of how a sex scene can be scorching hot with almost no nudity (except for Lowe's admittedly fine ass :)

Oh, and one other thing. I'm not sure how many '80s movies you've seen, but movies made during that decade routinely had very hot sex scenes. Two that immediately come to mind are both of Tom Cruise's scenes with Rebecca DeMornay in Risky Business -- including the justifiably famous train scene. Also check out Gibson and Weaver in The Year of Living Dangerously and Harrison Ford and Kelly McGillis in Witness (or McGillis and Cruise in Top Gun -- McGillis had an amazing rack :-D) Or Jennifer Jason Leigh and Phoebe Cates's scenes in Fast Times at Ridgemont High. If anything, I think the sex scenes are inferior nowadays -- more porn-y and less erotic.

You haven't seen many 80s movies, I take it.

This will be the high point of my day; it's all downhill from here.
