I'm not going to go into this and write a large well rounded review as there are other reviews that do this, im just going to give you the main point this film comes down to.
I sat through the whole film and enjoyed it, it wasn't what i'd call thrilling or exciting but was enjoyable and felt realistic for an event that could actually happen. As a result the end of the film came and an on set of "is that it" dawned on me. This didn't ruin the film for me but it leads me to my main point, as someone interested in science who studied this sort of thing at A level it was a very entertaining and had a very documentative feel to it. You feel like you learn how easily something like this can spiral out of control and is very much entertainment for those of an academic nature and a nice surprise for others.
As a result if your a film buff looking for exciting plotlines and stories you'll probably be dissapointed with it generallly. The acting seems to focus on realism for the situation but theres nothing to exciting about it as the story doesnt really call for it. This isn't another disaster movie for action/thriller fans, If however you take an interest in science, media, medical, Disaster planning or just generally enjoy to broarden your mind then this is deffinately worth a go.
