Reboots. Revivals. Returns.
It's hard to classify the craze of TV shows being brought back to life. Some return with all-new casts and storylines, and others pick up exactly where the original show left off as if nothing happened.
But as the new "Roseanne" and other reboots before it have proven, they can be a hit with audiences and critics alike. Even though "Roseanne" was canceled last May after star Roseanne Barr tweeted a racist remark, it premiered that April to over 18 million viewers.
Reboots can also be duds, though.
Business Insider looked at 27 notable TV reboots and ranked them worst to best, based on how well they did with critics (using critic scores from review aggregator Rotten Tomatoes).
We based the ranking on the average of the reboot's available season critic scores on Rotten Tomatoes — most only had one season. We also included the average critic score for the original series, when available, for comparison. In the case of ties, the reboot with the higher audience score came out on top.
