We waited many, many decades for the original Blade Runner movie, the influential dystopian sci-fi drama starring Harrison Ford and based on a story by Philip K. Dick. And when Blade Runner 2049 finally arrived in 2017, starring Ryan Gosling and featuring Ford in a crucial supporting role, it wasn’t worth the wait. But its technical effects are quite good, and so are some of the other supporting cast members, including Robin Wright and Edward James Olmos. But overall, as sequels go, this is the sci-fi equivalent of The Godfather: Part III. It’s more interesting as more time passes, but it’s embarrassingly inferior to its predecessors.
