And Steve the Drunk seems to be a drunk in this show as well.
I think both Hart and Cohle are good detectives in different ways. Hart seems to be the chosen one of that department, so he has to be doing somethings right.
The more Deadwood and The Wire actors the better, Brother Mouzzone, Lester, was in this as well.
It's obvious Cohle is the better detective and more in tune with the case. Hart is more of the politically savvy guy vs. being a criminal profiler.
