Netflix has Dexter Season 1 and 2 on instant play. My husband and I watched it. We're addicted. We finished season 1 in one week, despite being so busy with work and everything else.
We're now about to watch season 2. I can hardly wait. When Dexter first came out, I didn't think I would like it. I mean, come on, he's a serial killer. But, I love Michael C. Hall here. They do a perfect job. If you haven't watch it, you should.
