I accidentally stumbled upon Free Fall about 3 months ago, and I have been watching this movie every free chance I have.  I can't believe the impact this movie has on me.  Not only it has a great story line, I just love watching Max and Hanno; they have such chemistry.  Since then I have been watching all of Max's movies, including Napolla, the Wave, Urban Explorer, Red Cockatoo, My German Friend.....to name a few.  I have also becoming so interested in learning German.  I just love the sound of it - maybe because Max is speaking it.  I have taken up learning German on my spare time.  
Mariska, like you, I love hearing Kai calling Marc "pussy"
I always skip the Marc/Bettina love scene
I also stop watching after the hospital scene
I was reading all of the comments, and can't believe how many people are just like me out there.  For a while, I was wondering if this is normal since I have NEVER liked a movie this much before.
