I gave it an 8, Why?
Spoilers
Because they actually go through with the *beep* orgy.
I was so sure they wouldn't, I was so sure they would go with the old "true love" *beep* In the end, no one had to grow up, no one had to confess to anything.
It felt like a breath of fresh air that the blonde didn't walk in on them or anything.
It was just a couple of friends having an orgy, no moral, no holier than though life lessons, just a bunch of people enjoying their time here on earth. Somehow, it was more realistic than 90% of the romantic comedies out there.
