Doesn't anyone like a credible plot line these days? Total rubbish from beginning to whenever I gave up watching it (I was partly hoping against hope that it would improve and partly enjoying seeing how much more idiotic the script could get). Do not watch this garbage unless you have a fascination to see how low film-making can get.
Lots of good acting wasted on a convoluted, illogical and ridiculous plot. We're supposed to believe all of these unconnected characters connect on what is probably the dumbest location to find an unknown witness who could have been protected in any number of ways. The ending shows they were willing to destroy the whole train anyway so why didn't they do it early on. Who was the mystery lady? Who did she work for? How did he find her? Was the captain involved.? Don't waste you're time trying to figure it out.
This is a mainstream standard movie. You have seen it all before. You have even seen Liam Neeson tons of times in that role before. So if you want a cliché movie THIS is the Big deal.
Lack of logic but is entertiantment.Just watch get fun dont judge why?
