I felt the same. I watched it all the way through and understand that it laid the groundwork so a better show like The Wire could be produced. But I agree with you. I hated Tony and basically everyone he associated with and was glad to see some of them killed off. I guess that means it was well written but its the reason I haven't bothered to rewatch.

The Wire on the other hand I've seen completely atleast 5 times and always notice something new.
