This comparison is prime example of the problem. They wanted to recreate the scene from the original for nostalgiabait. All right, whatever. Of course, you can't use the old actors, and had to do shitty CGI Arnold, fine. But the new version clearly look so much shittier in every way - the lighting, the colors, wardrobe, everything. I mean they had the source material *right there*. All they had to do was to copy the frame of an old low budget action film one to one. No creativity required. Just copy.
They couldn't even do that. Hollywood is dead.
