The lights are on
I'd give it an 8. It had me laughing in some places, and the zombie killing was fun, but I just didn't feel like there was enough of it. Like the trailer had mislead me, somehow. A few parts slowed to a crawl, but not for very long. And of course Woody Harrelson was great.
And I do agree that the movie had one of the funniest cameos ever. I also enjoyed the stuff that came after the credits. I hope y'all stuck around for that.
