I just found it dreary with hackneyed dialogue and trite notions about the Success Ethic. It’s really a parody of gangster films. 1983 films I prefer include Zelig, The Meaning of Life, The Right Stuff and A Christmas Story.
I think you just didn’t want to like it. It’s a fun movie. Of course it’s exactly the kind of fun movie literati don’t like, which is a large part of why it’s a great movie.
