Just got back from the cinema. Forget it's called Die Hard and treat it as a normal over the top action film and you'll enjoy it.
To be honest, if they want to call this Die Hard then the two Willis films advertised before it should called Die Hard too.
That's the problem really. Only 1 and 2 are really Die Hard movies. After that they become generic action films with more explosions, less realistic violence to get the teen audience and a sidekick and they just happen to have a character called McClane in them.
