I didn't like its overly biblical take on the universe with replicants as angels and Wallace as an old testament God, Luv an allusion to Lucifer.
Joi, on the other hand, could have been a high point. We'd have several "layers" of real with a hologram, an old Nexus 6 replicant like K and the new obedient replicants like Luv and her ilk.
But that vein was (AFAIK) just left as a gutpunch to K by the commercial hologram and didn't feel like the central theme in any way. For me, the "you play beautifully" line was the lynchpin of the old movie.
Having said all that, I only got to see it once and I may have missed something. I was awed by the movie back them, but not moved. Still left it as one of the better cinema-experiences of last year for me.
