Many of the worst television shows in history have originated from some seriously questionable concepts that make you wonder how they ever got produced in the first place.
ABC's "Caveman" series in 2007, for instance, was based on characters from a GEICO commercial — actually — and Fox's 2014 reality show "I Wanna Marry Harry" saw 12 women compete for the chance to marry a Prince Harry look-alike who they thought was the real Prince of Wales.
Both shows were critical disasters and, thankfully, each lasted only one season — as many of the worst reality shows, dramas, and sitcoms have.
To find out which programs critics hated the most, we turned to review aggregator Metacritic for their all-time list of the worst TV shows (though data only goes back to 1995), which ranks show seasons based on their composite critical reception.
Check out the 50 worst TV shows of all time from least to most objectionable, according to critics:
