If you enjoyed the original "Bladerunner" movie, don't bother with the sequel. Long, tedious, boring, endless dark CGI depictions of a wasteland landscape, shallow characterizations, etc., etc. Two hours and forty-five minutes of film that doesn't live up to all the hype.
Remember the beautiful 'replicant' Rachel? And the mysterious Hispanic cop that left the origami animals lying around as a calling card? They both make cameo appearances.
Seems 'Rachel' and 'Deckard' got together in the Biblical sense and produced a pair of off spring. Rachel' was the prototype 'replicant' who could reproduce with a human. Now the hunt is on for the kids to study them and get the program running again.
I just gave you the gist of the movie. The rest is slow paced melodrama interspaced with a few intense action scenes in case you were falling asleep.
I give it two kernels out of five on the popcorn scale.
