Well BR is not an action movie it is a artistic scifi, noir, detective drama.
It's a good movie for it's type, you just have to watch it a very times to understand it.
Also, the music from the music is great, Blade Runner Blues is one my all time favorite pieces of music.
The Greek composer Vangelis did 'Chariots of Fire' and 'Blade Runner' in two consecutive years. Good peak.
