Really Should Have Got Another Year....
This show is just the right kind of melodrama that I think by the third season it would have caught people's attention, similar to Breaking Bad in its third season.
Season Two was a bit cluttered with characters, in my opinion, but some were set to be weeded out in Season Three and perhaps with a strong new character in a key role, also like Breaking Bad, Boss might have caught more viewers.
The loss of this show is a real shame, it was very compelling and Kelsey Grammer only gets better as he gets older.
