I was looking forward to this, and wanted to like it (love intelligent sci fi, aliens etc). All the sections set in China were outstanding- really excellent acting- brilliant. Unfortunately as it went on and centred on the young physicists, it became less and less believable. The acting varied hugely, as did the acting styles. The characters storylines became less and less plausible, and I cared less and less what happened to them. Bring on the alien invasion!
