In the top 5 of the Worst films I've even seen, tries to make us realise how much we depend on technology, but just goes no-where, it's one that builds up suspense so you keep watching waiting for something more to happen but then it just ends abruptly like the producer couldn't think of an ending!
do not bother watching it, unless you love wasting time that you'll never get back, I'd give it no stars if I could.
