Firefly was the series, the movie Serenity was great !! The only problem is everyone moved on to new stuff afterwards. The Captain is now the star of the TV series The Rookie. Unfortunately, the rest of the crew didn't find new work except for the dead pilot, who is now in ST Discovery. Firefly only had one season, but, the clamor of the fans caused it to be reconsidered and finally prompted a really good movie - see it if you can through Netflix or other Hulu channels.
I saw the movie first, when I was overseas in the sandbox. Thought it was great, then I found out there had been a series! Serenity tried to wrap up loose ends, too bad cast members had to die the big death though.
