I'm usually a sucker for movies about old guys trying to recapture their youth. I'm the target audience, after all. For the first half, that's the sort of movie THE WORLD'S END is, with a group of middle-aged British guys including Simon Pegg (who co-wrote the script with director Edgar Wright, as usual), Nick Frost, and Martin Freeman, trying to recreate the legendary pub crawl they attempted when they graduated from school twenty years earlier but failed to complete. It's funny, poignant, and works really well.
Then the plot takes a bizarre, abrupt, science fictional turn, and that works pretty well, too, although I liked the first half better. It really does feel at times like you're watching two different movies. But if you enjoyed Pegg and Wright's earlier movies like HOT FUZZ, SHAUN OF THE DEAD, and PAUL, you'll probably like THE WORLD'S END, too. I did.
