Basically they are making fun of the movies they like. For me, it works. I don't expect something beyond stupid humor and I find their stuff to be quite funny. I've always loved British humor too though. Yes, the movie did get a little too serious at times for a "comedy" but Shawn of the Dead did as well, sort of split between gorefest and comedy also. I wouldn't call them the best movies ever made, but they are at the very least, entertaining for 2hrs (to me anyway). I also have to now see their NEW movie "Run, Fat Boy, Run" LMAO!
