I honestly don't know why they kept Scott Caan at all. He's the one who turned me off of watching in the first place and I continually cringe when I see him
He doesn't do too much fighting, does not solve any cases and is not funny.
Plus the show does not have anything similar to the original show except for the names of the characters.
On the other hand I do love the rest of the cast as long as I don't compare them to the original cast.
