I very rarely watch weekly episodes of any tv series with Games of Thrones being the only exception. I usually tend to have a fortnight cycle so I can watch two episodes together.
Timothy Olyphant was excellent in Deadwood & carries on his great acting in Justified playing the role of Deputy US Marshall Rayland Givens. I also like the Boyd Crowder character played by actor Walton Goggins.
There are only 13 episodes per season with no what I like to call filler episodes (the episodes which do not contribute to the main story through the season).
I've also been catching up on Mentalist which has also been renewed for another season. I still feel they should have ended the show with the culmination of the Red John story.
Unlike Justified, Mentalist has quite a few filler episodes (this happens with all shows that have a 20+ season run of episodes) I tend to get bored with longer run episode shows after a couple of seasons & give up but I have stuck with the Mentalist. I'm hoping the renewal for next season gives the writers a chance to end the series.
