There are fourteen episodes of Firefly that were made here, before it got cancelled. And there are 20 episodes of Firefly in the other dimension, therefore, six episodes made there that weren't made here.

In that dimension, people in the movie and Television business make opposite decisions to what they do here. So, Firefly didn't get aired in the wrong order and thus, didn't get cancelled. Return of the Jedi was the best film of the STAR WARS trilogy, and the prequels were way better than the originals, in terms of acting, direction, sets, plots. etc.

But then again, Doctor Who is a teenage angsty mess over there, so it's not all good stuff. And Arnie is considered a Shakespearean actor.
