The comic is actually based off of the movie 28 Days Later (and later released book 28 Days Later, The Aftermath, and even later released movie 28 weeks later). The original movie 28 Days Later beginning sequences are a 100% match for how The Walking Dead started, a guy wakes up in a hospital days or weeks after the infestation has started and is clueless. The only difference being is that it was set in London. I liked the original movie, and I liked the new show, but I really wish the writers of the show could have been a little bit original in their writing for the beginning sequences. (yeah, I know The Walking Dead comic is a different release name than 28 Days Later, but where do you think they got the idea from?)
A better question might be, have you seen 28 Days Later? Cause if you haven't you should. And most definitely before you read the comic book.
And while the topic is zombies, you should also read the book World War Z. The guy who wrote it is Mel Brooks's son or nephew. I can't ever remember which one. But it is a really good book.
