It's not a museum, unless there's a dark room with a bunch of mostly empty chairs lined up in front of a projection screen showing a slide show or documentary (or really both at the same time) with an overly enthusiastic narration covering the history of the subject.

Sometimes you can't even get to the displays, without first at least walking through the room.

Whenever I walk by the vaguely muffled sounds of someone watching a movie in another room, I get nostalgic for childhood visits to museums.
