Thought it was a good film. As someone has also stated, if it was on at the Cinema again Id pay to watch it again. Although Id give the huge Nandos meal before it a miss.
Also for anyone who already has it on DVD, towards the end of the movie when the film flips to Robs recording of him and Beth on the Fairground wheel, look carefully at the sea behind Beth and you'll see the monster drop from the sky into the sea.
