So imagine if in Shaun of the Dead, Liz was 7 months pregnant, they'd just done their monthly supermarket shop and instead of going out, they'd decided to hole up in her block of flats. And the zombies don't bother to attack (there are no zombies in Phase 7, but it has the feel of a zombie film). But the rest of the apartment block goes a bit mental. That would kind of be along the lines of this film. It's funny (most the humour is pretty subtle but there are a few real laugh out loud moments) and it is quite bonkers but in a really enjoyable way. It's maybe not fair to compare it to SotD, it's not quite in that league, but it is a really enjoyable film with some great fun performances that's worth checking out if you get the chance.
