Bullet Train (out Aug 4) is set on the famous train from Tokyo to Kyoto. On board is the son of a famous crime lord, a locked briefcase containing $10 million, and a bunch of experienced assassins with missions to complete. The colourful train, hip soundtrack and famous actors provide a “gloss” that mask its flaws and unoriginality. A friend summed it up best – “if this was on Netflix and starred a bunch of nobodies, it would be terrible.” Grade: C+.
