Part of the reason I wish they'd show them in theaters is that it would be cool. It used to be normal to show short subjects before movies in the theater, but now it's vanishingly rare -- only Pixar really seems to make theatrical shorts anymore. And that's a shame, because it's cool to get a bonus before the movie. At least it's better than an endless barrage of commercials and trailers.
How will we know when to silence our cell phones?
