I watched this show for the great chemistry between Reese + Finch, and Carter + Fusco. The team of four was great. By the end of season 2, I felt we were finally getting to the core of a well established four-way partnership. Then Season 3 happens, and Carter's been sitting in a squad car peeping on dirty cops for 5 episodes. Fusco's been...God only knows, because they won't show us.
All I can say is, it's clear the producers of this show are demanding the sex appeal be cranked up. Hence why Shaw is now a regular (far...FAR too regular; I mean, her character is fine, but please stop shoving her down our throats), why Root keeps popping up and why Carter's getting 5x the screen time as Fusco. Which is saying a lot, since Carter's barely been in any episode save one.
It would be nice if A) They just removed Fusco as a main character and DID something with him to put us out of our misery, or B) put him back on the railroad tracks and him meaning again, rather than being an occasional intel dispense and comedy club routine. He didn't show in the previous episode, and only showed up for 15 seconds in the week's episode. So, producers, are you going to give his spot to one of these new 'main characters', or are you actually going to do something with him?
