If you have a Netflix account you can skip the commercials, but the last few episodes are not there yet. One way around that hitch is to watch Netflix up to the last episodes and then switch to AMC’s replays.
That’s essentially how I caught on to the series, is by watching the mini-marathon reruns AMC provided of the first two seasons while DVR’ing the new eps of season 3 until I had caught up on everything.
Even though I had watched the show as it aired I felt the need during the break in Season 5 to “catch up” by way of Netflix and a nearly solid watching schedule of my own. That really helped clear up some things that weren’t obvious/blatant in the original airings.
