The only bad thing I can say about this film is the fact that it took nearly four years for it to reach the US. The tag line pretty much sums it up -- what was intended as a one night stand turns into more than the participants expect. Sexy -- definitely (I may never look at wildlife documentaries quite the same way again); funny -- in many places hilarious, especially when examining the Mars/Venus aspect of burgeoning relationships (toilet seats, dressing time); and surprisingly sweet. The stars are charming, attractive and very real, and are ably supported by the rest of the cast, particularly the actress (whose name I now can't remember, my apologies!) who plays the cabbie who doubles as a relationship counselor.
There's a saying that life is what happens when you're busy making plans -- perhaps love is what can happen when you're busy having sex, if you let it. Well worth your time, and share it with a friend.
