I stepped in to watch it in 1982. Didn't like it much. But rewatching it over the years, it grew on me.

I wonder if part of that is that Blade Runner doesn't optimize for the first viewing. Once you already know where the plot is going, your attention is free to wander into the production design, sound, background activity

The re-cuts are definitely an improvement on the original theatrical release. It's a matter of taste, but for me Director's Cut is the better.
