Went and saw this yesterday and was disappointed. The main issue was that it wasn't funny enough, too serious for the most part and nowhere near as many quality one liners that they had in SOTD and Hot Fuzz. They hinted at those two films a few times in the movie but still it wasn't enough. Glad I saw it but I won't be buying the DVD when it is released.
Watched Hot Fuzz last night just to remind myself how good these guys are when they get it together.
