I finished Season 1 last night and I'll echo Targets Guy's sentiment in that I was disappointed in Season 1, as well. I think the casting was great and I enjoyed the characters (save for the two old dingbat ladies), but there was too much law enforcement corruption at so many levels in the story line to make it believable for me. Its a TV story, I know, but too far from reality to make it credible.
I'll watch Season 2 when it breaks and hope for more realism.
