There is one problem with the movie and it isn't actually WITH the movie but a broader problem that Hollywood needs to deal with right NOW; they need to stop telling us so much in previews.
I would have been much happier if I hadn't KNOWN this film was about robots? As an avid movie goer I should, at least, have the opportunity to not know. If I want to have a movie spoiled there are tons of reviewers willing to do that for me. I didn't need to go see the Harrison Ford/Gary Oldman movie, Paranoia, because the previews pretty much told me what was going to happen in the film. Even more egregious are the previews for the remake of Carrie, the new Vin Diesel film, Captain Phillips...hell pretty much every single preview I've seen for months.
Hollywood thinks we are stupid and won't understand if they don't spell it out for us. Please, stop! It actually stops me from going to certain movies and I am sure I am not alone in this.
How many of you recall high school as the pinnacle of your life? It is to be hoped very few. Even so it is a certainty that you know someone who feels this way. They have never gotten past their "glory years" which were usually far less glorious than they recall. That is the starting point for this film.
Pegg plays Gary King, the vaguely goth high school superstar who decides (at a little too much length) to get his old friends together to relive their youth via a particular quest. He wants them to return to their hometown to go on a pub crawl--having a pint at each of a dozen pubs, culminating at The World's End.
Frost is decidely NOT Ed from Shaun of the Dead in this movie, instead being cast in the sober, responsible role. He and Gary's other friends are all gainfully employed, fairly successful and only moderately nostalgic for days gone by. But with clever lies and manipulation Gary gets them all on board for the trek.
All along the way gags ensue. Much like Hot Fuzz before it this movie will improve upon second viewing. Some of the early jokes are put into context by what happens later. That is one of the beauty of the "Cornetto Trilogy" all the films stand up well to repeated viewings.
There are some lessons in this one but these are never used as a bludgeon. And also the ending sort of leaves it open for interpretation what, precisely, these lessons are. Maybe it is ok, under some circumstances, to live in the past? Perhaps when the present is miserable?
But life lessons are not really the point here in any case--humor is and The World's End gets that part right. It does it in a way that induces more chuckles than uncontrollable laughter but that is by design. It is to be hoped that this isn't the final curtain for this group working together.
