Saw it today, and really liked it. Like Shaun of the Dead and Hot Fuzz, it wasn't necessarily laugh out loud all the way through, but there were lots of funny moments - and probably more poignant ones. I loved the little details that it will take a rewatch to fully appreciate - the numbers in the pubs, the way the pub name relates to what happens - and the nods back to previous events (when the Cornetto finally appears - brilliant). Also, without being too chin-stroky, I really think Pegg and Frost have grown have actors. A fitting end to a marvelous piece of work.
