Poison Ivey (not the plant)

Just saw on the tv a preview for the movie "Poison Ivey". The preview implies Drew Barrymore has hot sex with various people. And she looked hot in it.

So I googled it, and it says here:

Runtime: Argentina:90 min / USA:88 min (R-rated version) / USA:93 min (unrated version)

So, anyone seen this movie? Is it worth downloading? And does 'unrated version' possibly mean extra/better hot sex?
