I saw this movie twice last week, and I absolutely love it! I got my dad to see it with me my second time, and he thought it was great, too. I love British humor, and this movie was full of it. I agree with the people who liked the part with the ball; that was definitely one of the funniest parts.
I recommend this movie to everybody! I'm a bit squeamish when it comes to sound effects, and Shaun of the Dead got to me a couple of times, but it was worth it.
