What TV series was cancelled too soon and deserves another season or two?

My first pick is "Firefly". Such a witty, creative take on Sci-Fi adventure. Great cast and characters. Loved Kaylee and Enara.

Then, of course, there's "Big Bang Theory". That show made me laugh every minute. "Young Sheldon" was great, but out grew its main character.

"Resident Alien" still makes me laugh. Great cast and characters. I especially liked Big Black and Judy. Maybe the storyline just ran its course.
