Kwon, yes it is impressive how far AI has come. I can say to recreate all this via CGI and 3D work would have been a monumental task, and I doubt it would look as impressive. But this is still not nearly as good as real life, with believable lighting, shadows, reflections, etc. The scene where Keanu and his buddy walk on the road at night looks like they had a green screen behind them that was keyed out and replaced with a background. It did not look like they were in that environment.
The acting also feels very scripted, not natural. Like everyone has been given a few lines to say, then pause, wait for the other character to speak, then respond, etc. No real emotion here. If the goal is for everyone to come across as an emotionless terminator then I guess they pulled that off.
