Aren't the special features awesome? I like that they're usually both funny and incredibly entertaining. I have to agree with you about Hot Fuzz being the best of the Cornetto Trilogy. Or should I say the The 91 on Rotten Tomatoes Trilogy, as per Edgar Wright? ;)
I found World's End to be entertaining but not as funny as the previous two. A good romp all the same. Loved seeing Nick Frost beating the crap out of people with a stool!

Some of those sand castles look pretty awesome!
