Are you talking about the National Museum in Edinburgh? Is it possible it's been revamped in the last couple of years? Loie and I were there in 2000 or so and thought the prehistory rooms one of the worst presentations of material culture we've ever struggled through. Maybe it's diferent now, I don't know.
When we were there, the lighting was so low many objects were very difficult to see. The glass shelves allowed objects to cast obscuring shadows on those below. The notes were in white paint on clear plastic and impossible to read. They were down below the cases at ankle level and we had to constantly be stooping and squatting.
The objects were grouped by type: all ceramics together, all stone tools together. Thus, it was impossible to get any sense of how different objects related to each other, or of a "culture" in any particular time or place. The damn place was like a huge jumble sale in somebody's dingy basement. Bad bad bad.
I don't remember any educational films. Maybe we missed it? Or is it new?
