Fatal Attraction

Just finished watching Fatal Attraction on cable.  Even though it's such a famous film, I'd never watched it before.  But two things puzzle me about it:

Fist, I know this film has been rated R in several countries, yet here the cable channel offers it in mid-afternoon, and it's not even one of those expensive channels like the porn ones.  I wonder though why was it rated R.  The only thing that one might object to is seeing Michael Douglas' ass.  Yeah, not even one female nipple, just Michael's ass.  And even this scene was quite odd.  He was taking a shower but the shower curtains were not completely closed, so you could get a peek of his bottom.  But who takes a shower like that?  I don't know anyone who doesn't mind splashing water all over the room.  I think everybody is careful for that reason to completely close the curtains.

Second, at the very end they finally get rid of Glenn by killing her in their own bathroom.  Next thing you see is probably the cops in front of Michael's house giving him a handshake and leaving him so he can go take a sleep (by the way, Michael is now wearing completely different clothes).  I mean, isn't this odd?  There has been a violent death in the house, yet the people of the house aren't taken to the police station for questioning?  It's just like cops dropped by the house as if they were pizza delivery boys?  It doesn't make sense.

Ah, but all in all, it was quite a good movie.
