Adaptations of the children's books by David Walliams have become a sort of fixture of the Christmas TV schedules, and this was the third of these.

I enjoyed the first one 'Mr Stink', but I found this one to be a little dull if I'm honest. It has its moments, and the message behind it is good, but I didn't find the cast to be as full of big names as previous adaptations, and crucially for only an hour film, it dragged.

The lad playing Dennis does well and he is ably supported by the always fun James Buckley as a PE teacher and Harish Patel as Raj. I didn't find Jennifer Saunders role particularly funny at all though.

It is a well made adaptation though, and well worth watching on DVD.
