I just saw this and surprisingly, it's looking like it might be a winner thanks to the superb writers. A virtually unknown cast in terms of the Donnely boys and a good supporting team makes this interesting IMHO. The was plot's pretty predictable at times (Italians vs Irish) but the scenes with the banging soundtrack were delivered with pretty good punches. The end of the pilot episode was brilliantly bizzare and funny.
