Like S P A C E D? Like Shaun Of The Dead? Like Hot Fuzz? Like Scott Pilgrim? Like the quiet English village SF apocalypses of John Wyndham and their influence on Quatermass and Doctor Who? If the answer to one or more of the above is yes, you’ll probably like The World’s End.
Its heroes are certainly player-character-level in their mix of quick-witted improvisation and bloody-minded stupidity and extreme violence. And it’s definitely a one-shot.
It also has a fantastic example of how to create a slyly meaningful retro soundtrack. Which is in no way terrifyingly accurate to my own high school years. And life since. Nor is anything else in the film. Yikes.
