While this is a film with huge potential for failure – a slurring method acting loner, rescued dog etc. – this slow burner builds a tense and twisting plot and genuine foreboding atmosphere. There’s also a refreshing straightforward setting and story telling with no artsy tricks, crushing soundtrack or CGI, just the goings on in a bar, its assistant manager and people orbiting him. Slow and glorious for it, even if the pooch occasionally gets tiring.
