The whole lightning and shadowing of the environment is missing, how can that look better? The characters are lighted with blue colors, while the environment ist just bland grey
Watch this at 27:57, it looks extreme odd

The original cutscene with correct lighning on 360, at 27:12 to compare:

It seems that the background lighitng is what apparently "broke" there. I'm not a developer, but maybe it was not something they wanted to touch during the porting process.
In addition, all of us should remember that Halo 4 ran at 720p 24-30 fps on Xbox
360. Halo 4 on Xbox One has dips into the 30s at specific points with a 1080p upscale, despite being, what, 10 times more powerful(?) than the Xbox 360. Halo 4 was clearly developed as close to the metal of the Xbox 360 as possible for it to perform the way it did. That might be a factor in why the port turned out to be so mediocre in certain areas such as lighting, and the same goes for Halo 3. I'm sure we wouldn't see the dips we see in any of the Master Chief Collection games if the ports were done better, but none of these games were originally made with PC or Xbox One architecture (referring to CEA and H2A's campaign textures as well, which both experience FPS dips), and I'm sure 343 didn't have the time to perfect them, considering how MCC turned out in the end.
I'm just saying, I still recognize the sharper textures and draw distance.
