This movie proves one thing (much like Shaun of the Dead did): Zombies, can be funny. I loved this movie, if not the way the 'rules' often presented themselves. The movie also didn't take it self to seriously, or make the characters to serious, or to overly stupid (while keeping some stupidity), and I felt some of the cliches were washed away (if not made fun of). The appeal on a focus of a group of characters going differently, then it typically does in this sort of movie was pretty good to.
I also read about the pilot, an interesting note for sure, and probably a mistake to approach CBS with it. In the end though, it's probably better it became a movie, instead of a series. It'd have been drastically different, and probably controverted in guest stars, series pacing, etc... I certainly look forward to the sequel, and hope it can be just as good, if not better. Apparently, everyone involved with the first one, wants to be involved in the second one.
The celebrity mansion scenes were funny, I thought and Tampa's reaction to the celebrity, and what is and isn't connection to his discoverity of the celebrity and being a fan...hah...classic.
