For real...? Wow, I'm impressed.Blade Runner. You can't possibly be more underwhelmed than I was...
I suppose the fact that you watched it 25 years after it was released (assuming you watched it recently) may have something to do with it. It probably seems unoriginal (by today's standards... but consider what other films were like in the early 80's) and the FX may look a little bit dated compared to today's CGI-tastic films, but apart from that it is clearly a masterpiece.
