I still prefer 20-22 episodes. At least you have something new to watch for 4-5 months straight.
Everyone talks about the new 10-13 format being better due to not having filler, but the word "filler" in and of itself is debatable. One could argue there were at least 3-4 uninteresting (or "filler") episodes during the first season of The Orville, and that would already encompass 33% of the entire season.
I'm still convinced the whole point of moving to the shorter format is to reduce costs. Actor salaries have gone up over the years, cable/sat company expenses have risen (mainly due to broadcasting networks getting greedier by the minute), and likewise cable/sat subscribers have fallen, due to streaming services and cord cutters. So, what better way to reduce costs amidst rising expenses, than to order less episodes?
When you break it down, 13 episodes every 2 years would be about 6 episodes per year. Don't you find that just a little bit ridiculous? Even a tiny bit? Or maybe it's because networks don't want to commit to the science fiction genre. We're not talking premium cable HBO/Showtime mini-series or limited-run event series here. If you look at shows like The Price Is Right, or daytime soap operas... hundreds of episodes per year. Even other FOX primetime shows like Gotham and Lucifer have 22-26 episodes per season, for crying out loud.
