If you go that route, though, you won’t be watching with the rest of us in the U.S. The way AMC has it worked out is that those alternative outlets don’t get the episode until the day after the original airs.
If you’d like to access just an episode or simply want to pay for a season of The Walking Dead without the cost of a cable package, Google Play, Amazon, and iTunes are really reasonable deals.
So, if you want to purchase episodes to re-watch or want to keep that content with the rest of your library of TV shows and movies, this may be the best option.
