I like Patrick Jane a great deal, but the police procedural nature of the show didn't hold my interest, so I dropped it after two seasons. I've tuned in for season finales and premieres though, and I wouldn't mind revisiting a few other episodes I've missed.
I'm watching regularly again after having caught up with seasons 3 and 4. I especially liked the most recent episode, "Red Dawn"
. It was nice seeing an origin piece that took us back to when Patrick Jane joined the CBI. It also served as a bit of backtracking to set up an arc.
