How many would know about 2001?
Probably slightly more.
It's also an office where the majority age is 45+. I really think some of y'all are overestimating the amount of appeal this film had.
Hard sci-fi, sequel to an old film that also failed at the box office, and pretty lackluster marketing (IMO).
I think if they had released this on Netflix and got some better marketing them they would've made a bigger splash. I think audiences would be more likely to take a risk on a film if it's part of a subscription service they already pay for and doesn't require them to go to all the effort and cost going to a movie already has.
Edit: think about it. If you've never seen Blade Runner, you're probably not gonna watch the sequel. Putting both on Netflix might help.
Going to a movie requires spending $10 on a ticket per person, you probably aren't gonna go by yourself, so you need another person who has seen the first one, if you have kids you have to find a way to have someone to take care of them which possibly requires more money, you're probably gonna get dinner or something at the theater which means more money, and you have to set time out of your life to do all this. Why go to a that trouble for a film you might not even enjoy?
If it was on a streaming service people could casually watch it at their leisure without the need for all of that. They'd be more likely to take a risk on a film they might not enjoy.
