I didn't like that theyI just finished it, too. Yeah, it got pretty sluggish about half-way through....
killed off many of the good, albeit flawed characters, but let the one truly despicable character live (although behind bars it looked like). Also am generally unhappy about the degree to which suspension of disbelief is required by the viewers for certain characters, like V.M. Vargas and his operation in season 3, and Lorne Malvo in season 1.
