In fairness the film takes on a fairly difficult concept and to this end feel some sympathy towards it. However as far as films go this is drawn out. In some respects I suppose it is as expected. Lots of deep breathing and over done focus on a chap stuck down a hole. Thankfully, his moments of delirium,brings a little variety to the all too long and drawn scenario. Felt the film was more for the geek rather than someone wanting to see something enjoyable. I had hoped for a little more about the character and more to surround the scenario giving it build up. These aspects were lost. Given Danny Boyle's previous films have been of such an impeccable standard, this film has certainly not come up to that grade. Perhaps though taking such a minimalist theme was just a step to far.
