Reboot culture has resulted in quite a few revivals in the last few years, reuniting casts of classic TV shows and bringing a new story to the audience, but there are some shows that simply can't be revived after their end. While revivals can be some of the most rewarding experiences for long-time audiences, making them happen and ensuring they feel organic is tricky business. Cast members have to be willing and able to return, the story has to feel fresh and authentic, and the original chemistry may not be able to replicate itself after so much time has passed.
