It's also the case that nobody watched 2001 for the story. Hell, nobody even knows what the story is. People watched it because it was an impressive bit of eye candy (and still is). While Blade Runner had a story and some decent characterizations, much like 2001 it was still about bringing people into a fascinating world they hadn't seen before. Again, it was more about the what you were seeing than the story you were watching.
ST was different in that regard. We wanted a Star Trek story (and IMO, got one). I think they also wanted some 2001 in there, though (and accomplished that, as well). What I don't get is the characters being unrecognizable. They were a bit more serious, but to me they all seemed pretty much the same, save for Spock who got rebooted in the interim.
