Written by same dude that wrote Minority Report. Dark like that one,too
Philip Dick, who actually wrote the books both of those movies were based on, as well as the books Total Recall and BladeRunner were based on. All of the Philip Dick inspired movies are dark, and I think BladeRunner is by far the best of them -- in fact, the original version (not the director's cut) is my favourite movie of all time. I've read probably about 40 works of Philip Dick's and I haven't found one that doesn't have some sort of dystopic or uneasy/strange mood or twist.
