I went to see this film with a great deal of excitement as I was at school with the director, he was even a good friend of mine for a while. But sorry mate, this film stinks.
I can only talk about what was wrong with the first half because that's when I walked out and went to the pub for a much needed drink:
1) someone's standing on a balcony about to jump and so you send a helicopter to shine a searchlight on them??? I don't think so - nothing would make them more likely to jump.
2) local radio doesn't send reporters to cover people about to attempt suicide - again for fear of pressuring them into jumping - or for fear of encouraging copy-cat instances.
3) whatever the circumstances, radio reporters don't do live broadcasts from the 10th floor of a tower block. Radio cars don't carry leads long enough to connect the microphone and headphones to the transmitter.
4) the stuck in the lift scene was utterly derivative
5) the acting and direction was almost non existent.
I could go on, but I won't.
