Not sure how TM Feels about this, but you can head to
www.icefilms.info and watch the entire first season. I use IceFilms for EVERYTHING these days except for my Football addiction (College and Pro). If they had live streaming TV somewhere, where I could watch all of my Football live... I would never have Cable.
Link to the Walking Dead area.

Best website ever... and EXCELLENT TV Series. There are only 6 episodes in the first season, but they are well worth the 5 hours of your time.
