Look. Here’s a thing. If you make a zombie movie and make it a bit funny, it’s still not Shaun of the Dead. Unless it is actually Shaun of the Dead, obviously.
Like Little Monsters, this was another oddly disappointing comedy horror. The beginning was pretty good! The set up was alright. The zombie horde introduction went alright too. But then a group of lads that were able to polish off zombies left, right and centre decided to go through Moria on the way to the school (just how far away was that school anyway?) and it starts going downhill a bit from there.
The undead rapidly become unpredictably either really tough and fast OR totally stupefied without any real explanation. The tough lads rapidly become totally pants at zombie killing for no real reason.
