Saw this film again last night after watching the original in the cinema 23 years ago, as an 18 year old! I never forgot it though and recently bought the video on Amazon, and enjoyed it even more, maybe as it brought back a nostalgia for the 1980s.
'After Hours' is a film, that is meant for a certain audience. A Dark Comedy by Master Filmmaker Martin Scorsese, that offers shock value, some engaging moments, but, it's dark tone, will not attract everyone.
Honestly, it's a good surprise: as soon as the credits begin, the music wakes you up and rises you attention. It's easy and fast to understand that Griffin has a dull life: thus, he is open and not afraid of experiences.
