Never heard of The Vice before seeing it on Amazon, but then again, I don't keep my ear to the ground. Great series - up until Ken Stott's character leaves. Though Mr. Stott's last episode in the show is a great episode, you do miss him after that. He's a great actor (albeit 90% of the time playing a cop in anything that he does!) and lends the sort of dependability that someone of Patrick Stewart's caliber brought to Star Trek.
Even without the great Mr. Stott, the show remains quite watchable - it's just not the same.
Other than that quibble, The Vice is excellent , well worth checking out. Just no DVD extras on the Boxet, that's the only other thing.
