I simply cannot understand why everybody says "Run Lola Run" doesn't have any substance.
It does. It is about how tiny things can change our whole life. Now this idea might not be totally 
new, but still I would never call RLR a muic video without any content.
And I'm sure Tom Tykwer didn't make the music because he wanted to start a musical career.
In an interview he said he simply likes to be part of every step of the production, he likes to
have the control when making a film, so consequently he also did the music himself.
You should go and watch his other films "Deadly Maria", "Wintersleepers" or his newest one
"The princess and the warrior". They are VERY  different from Lola.
Anyway, nobody talked about the actors. Franka Potente of course is great and, in my opinion,
Moritz Bleibtreu is simply the best actor to have come out of European Film in recent years.
