If this show was on the CW, they'll make it to a 4th season (2/3rds of show's futures are determined on the 2nd season renewal... most don't make it that far) maybe a 5th, because then syndication money might happen. 22 episodes a season = 88 by the end of Season 4, the bare minimum for "stripped syndication", or a deal where syndication is allowed if the showrunner can finish 100 episodes within the fifth season by a deadline. (One possibility: CW has a DC superhero lineup. Their local stations would enjoy adding Gotham to their weekend lineups between sports matches and news.) But after 88-100 episodes happen, without high ratings, everything from there on is diminishing returns.
But this is Fox. If it's not the best, they meddle until they have an excuse to cancel it.
