There are so many to list so I will start with the latest one... Chuck.
We picked up season one and had a Chuckgasim over the weekend. This show is best started with watching the first episode of season 2 "Chuck Versus the First Date".
This episode really features all that is great about the show, still works as an introduction and doesn't spoil anything major.
When I first approached the show I tried starting at the beginning but the show did not grab me, I tried other episodes in season one and had the same result it wasn't until they gave away the first episode of season two that I fell in love with chuck. Going back and watching season one knowing what I know now has made the experience even better... as we like to say at dashPunk "This show suffers from the season 2-3 effect." That is to say by season 2-3 it found it's voice and the magic happened over the entire show.
True Blood season 2 premier was off the hook! I dont know how they come up with these endings that make you want more. I was hooked on Chuck right away but that may be because I work retail
I would suggest the show Dexter. After reading the show description I thought I would hate it but after the third episode I was in. I will post some music videos to give you an idea about the show.
