I took my 3 young children to see this film with a little trepidation, knowing it to be 2.5 hours long. Also, having read the books to all of them as bedtime stories, they each had pre-conceived ideas about the characters, portrayed so vividly in the text.
My fears were groundless. From the moment Dumbledore walked onto the screen in the first act they were mesmerised, their sweets and drink were left untouched as they were transported to the magical world of Hogwarts. The time passed far too quickly as they were taken on a roller coaster ride of fun and excitement.
The atmosphere created by Columbus is engrossing, totally convincing. I watched my children's faces as the story developed, from looks of pure delight as the Dursleys house was bombarded with owl post, to hatred as Alan Rickman's Snape bullied the kids and finally to tears as Ron was knocked from his Knight.
The film is not perfect, some of the children's acting is a bit wooden (not helped by the script, which tries to stay too close to the book), some scenes should not have been cut (lets hope we see some of these on the DVD !!) and some subtle clue's provided in the book for eagle eyed kids are missing, but none of this detracts from the overall experience.
As we left the cinema, the first thing my children said to me was "when can we see it again ?". "Soon", I replied. I began to realise that I had probably enjoyed the film as much as they had.
