Rat-a-tat tat

How this film affects you depends on your love for little rodents.

If you love the dirty little vermin, think Roland Rat was the pinacle of British television then you won't get much from this scare-fest without the scares.

The acting is sometimes dreadful, the set-pieces don't quite work, and the sight of a giant rat with the pace of a snail hunting down its pray is laughable.

There is something watchable here though, and if the thought of rats running around derelict tunnels and darkened corridors terrifies you, you'll get more from this than you bargained for.

Another average Kind adaptation.
