Yeah, there are certainly some drawbacks or discrepancies that should have been corrected, but then others left alone. It is amazing how much we don't notice in the lower resolution media. However, also remember that with the scene pacing, one wouldn't expect people to divert their attention away from the main activity at hand. That's why they didn't bother to waste time painting the underside of hand rails, just in case there's a low to the floor shot one day.
We have the luxury of time with the media in our possession; free to watch, freeze-frame, and re-watch to notice lots of things.
