Could be debated, potentially hotly:
Star Wars = Geek/Hipster/casual friendly, while also having nerd appeal.
Star Trek = Nerds only.
I love (real, non-reboot) Star Trek and only just like Star Wars.
Frankly, I don’t think Firefly deserves a place at the table with either.
Dr. Who is different and depends on whether the viewer:
Watched before 2005 or only after.
Don’t get me started on The Orville. Blech.
