In the beginning this was a great show to watch after years of the uptight Jethro on NCIS. It was quirky and almost like the writers gave us episodes that were almost tongue in cheek quality stuff. We had Hetty, Sam, Kensi and Callen. Eric was tolerable. They added Deeks and the show for me didn't miss a beat. And then the writers added Nell and started shuffling new characters in and out of the show and for this viewer the thing that attracted me in the beginning started to fade away.
I know a lot of you will disagree but that's fine. The show went from must see TV to DVR it and watch it when I have nothing else to watch.
