I just came back from this. In 2012, it was at the top of my most anticipated films list, and I was very sad they had to push it back for reshoots.
The early negative reviews shocked me and led me to lower expectations. I went into it without my high expectations of 2012...
That being said, I enjoyed the film, but it was nothing life changing. I think the cast was stellar and probably had too much firepower in terms of presence. The acting was straightforward. No one was bad, and i really enjoyed Cohen in the role.
I felt like it was a Dick Tracy-like story wrapped in a comic book. Nothing too memorable but an enjoyable film to watch.
