Still sticking with my three.
Tremors
Firefly
The Walking Dead
I'm rewatching Firefly right now and wow, it gets better with each rewatch. This is my third time through, and I'm really enjoying it. And some of the best episodes are coming up next!
I've been watching random episodes of Tremors, and I think some time soon I'm going to run through the series again, probably after I'm done with Firefly.
And I've been in the mood to rewatch The Walking Dead again, but I think I'm going to wait until October, just before season 2 starts. I'm hoping that season 2 is good, the firing of Durabont is making me nervous for the show.
