I just got home from watching it. I think that it was true-ish to the original. Not bad for a sequel but only reached a 6 or 7 of 10 for me (10 being the original). Here's why for me...
The visuals were to modern for me- read: to much CGI, action, explosions, etc. The original was so jam packed with a density of color, light, nuance, fogginess, darkness, and detail. This version had more than most, but not close for me.
The soundtrack and sound effects were more aggressive and far, far less atmospheric, nuanced, and without a perfect integration to the scene.
This film, for me, was an amalgamation of Blade Runner, Star Wars, and Mad Max. The situations and story line: many were factional and cliqued- NOT true to the original where the only 'group' was the 4 replicants. Otherwise, it was everyone for themselves- dystopian. I also did not get completely immersed in this one, as I still do with the '82 release.
I am glad that I saw it and will likely watch it again to absorb more of what was there. But I will always return to my dark master, the original
