I watched it yesterday, and I'm not sure I've fully digested it yet, but I think Joe's actions aren't really guided by logic or reason at that point. He's driven by his feelings. What's happened has triggered formerly unknown emotions in him and he's struggling to deal with them.Well, if Joe had never gone looking, Decker’s daughter would have remained safe. Why leave breadcrumbs if they could only endanger the cause? The premis of the story evaporates.
The original Bladerunner movie already wasn't exactly action-packed; by comparison Bladerunner 2049 is really ponderous. But the absolutely stunning visuals created a really strong impression of a cold and lonely world in me. I don't think I've ever been to a movie where the audience was so silent throughout the entire movie. It felt like everyone was overwhelmed by a strange reverence.
Perhaps I should mention that the original Bladerunner is my #1 favorite movie of all time. I don't think the sequel will change that, and I doubt I'll watch it as often as I did the original, but I feel it's a worthy successor. Who except Denis Villeneuve could have pulled off such a movie? (Well, perhaps Christopher Nolan, I guess...)
