I had high hopes for this film. The trailer makes it look like a grown-up, big screen version of Horrible Histories. The cast list is impressive so it appeared a sure thing. Sadly, the reality of it is very different. I kept waiting for it to move up a gear but sadly it never does. Also, I don't understand its need for a 15 certificate (apart from some swearing, perhaps?). The only scene that is laugh-out-loud involves the leads trying to dispose of a dead body from a great height. Had the film been more along this line it would have been far funnier. Its a real shame when you consider the talent on-screen who all have major t.v. & film credits. One to avoid I'm afraid.
