Two friends of mine whom I normally trust 100% with their judgement of films (similar taste) were very fond of it, so I gave it a try. I could say the german dubbing ruined it for me, but I don`t think that was all. I`ve actually read some of Miller`s "Sin City" graphic novels and liked them, so I`m not biased against the "sex and violence", etc. 
But to me the originals had much more heart.
The film looks like a sloppy "best of" to me, without any real connection to the characters it`s depicting. They are just some unlucky bastards the camera seems to focus on. 
Didn`t appreciate Rodriguez before (From Dusk Till Dawn was a bore to me), and it hasn`t changed.
