loved it! and dsjones is right: the version I read Loki did lose his eye in the shootout. The version I have is what they shot and is in the final movie. and I read palostick's version also. But it was a damn good movie.
The ending is brilliant. Gyllenhaal's performance is one for the ages -- stark, brutal, efficient but caring at the same time. I smell a nomination -- and barring any last minute upsets -- perhaps even a win. Very Doyle-esque.
