Very good film

Rating: 8/10 (16 March 2019)

Tension, great acting, convincing story. No stupid superheroes, no unnecessary CGI, believable action and no cheesy music.
Someone has just reviewed this with a '1' and I'm starting to realise that film/movie reviews are valueless as half of them are wrong - the challenge is working out which half.
I think the answer is that 50% of the reviews are 7-8 or above then you can safely ignore all the negative reviews as they are inept.
