STIFLER!
I walked by my 16 yr old Daughter and BF while they were watching this on Netflix and I said 'is that Stifler?' and they had no idea who I was talking about. I said you should watch American Pie - funny movies. They won't. Any movie I recommend is an automatic no watch for them.
Anyways, this movie is pretty good. Along the line of the Dexter TV series, with a hint of incest thrown in.
Definitively worth your 90 mins.
