A dire British misfire about three fiftysomething friends who embark on an Interrailing trip in memory of their dead buddy, Off the Rails is cringingly dreadful stuff even by the low standards of the ash-scattering dramedy road trip subgenre. Bickering middle-aged women obsessing over travel arrangements is not entertainment, it’s a living hell. On no account should this be shown to the rest of Europe or else they’ll just concrete over the end of the Channel tunnel and have done with us.
