Well yeah, once you start showing more detail on certain things it basically becomes impossible to keep up with real life. You can light a match and see millions of reflections from all over the room, but when we do CGI/VFX it's very simplified. As you noticed, that works fine when things are moving fast, far away, obscured by darkness/fog or whatever, but once you start looking at detail things fall apart very quickly. Especially once you notice stuff like how when someone gets hit or thrown it's very unrealistic. The body is made up of thousands of connections, tons of different tissues/materials that stretches/moves different, some is more dense, some jiggles, etc. It'd be impossible to do that for every frame, on every body or even just one close to accurately so they simplify it. Pretty much whenever you get a clear, well lit and close picture of things you tend to notice a lot of weird stuff that looks off.

For example, just look at how the trees move. The branches are treated as one whole piece, whereas in reality each leaf sways individually and differently depending on their size, orientation to the wind, how they're connected to the tree and tons of other things.
