Why wouldn't it?
One is an image saved at the 480 resolution that's stretched to fit a large format, on a television with far more pixels than it natively uses. Most modern devices and televisions will attempt to "upscale" the image, so it doesn't blur out of existence. But it certainly doesn't look awesome at any kind of realistic viewing distance.
And it's not like movies and other features were animated or filmed at the native resolution of the time. They're created at a MUCH higher resolution, and then the theater prints were at a lower quality (which vary wildly depending on the quality of the theater), and were released at television-level qualities in formats that could handle it.
You think the tape inside a VHS tape was the same resolution as the film used to capture the image in the first place?
The actual resolution of films hasn't really changed much in decades now. Digital filming might change that, but actual film is about the same quality now as it was in the 70s. Only the market-side capabilities have changed.
Anyways, you all are horrible, @#%^ed up people
