I'm not a big fan of the character, but I like the dark and mature universe of the comic. The adaptation seems to me quite faithful to what I have read.
The costumes, the location, the actors, the script, all the ingredients were there to make a descent movie.
The only problem is the lack of talent of the directors (although two). The acting is not very coherent. There are a lot of weird and uninspired shots and the cutting reminds me of Sam Raimi's early work.
It's less mature and violent than the previous one, it has lost some of the toxic mood there was with it's psychopath hero and most murders are off-screen. The actor has been replaced by another with a more pleasant physique, but without the nuances of his predecessor.
Monica Bellucci doesn't bring much to the film, Miriam Leone (the hero's girlfriend) and Valerio Mastandrea (the inspector) do a good job.
