[SPOILERS for those not caught up on Gotham ahead.]
Gotham season 4 is airing on Thursday evenings this fall, following FOX's decision to fill the DC Comics-inspired TV show's old spot with the network's upcoming live-action X-Men TV series, The Gifted. After releasing the official Gifted trailer online, FOX announced that its Fall 2017 Monday evening lineup will pair Gifted up with another comic book TV show adaptation in Lucifer, rather than Gotham.
Over the course of three seasons, Gotham has become a steady ratings source for FOX, even as its fanbase continues to debate the show's many twists and tweaks to the traditional Batman mythology. FOX officially ordered Gotham season 4 last week (at the time of writing this), ahead of the show's season 3 finale airing in June. However, with Gotham's ratings holding steady rather than growing right now, it makes sense that FOX would instead hand its prime Monday spot over to The Gifted, in order to help the X-Men TV show attract a larger audience, right out of the gate.
As a result, FOX's Fall 2017 lineup has Lucifer season 3 and The Gifted season 1 airing Monday evenings at 8 and 9 pm EST, respectively, with Gotham season 4 airing on Thursday evenings at 8 pm EST. FOX has Seth MacFarlane's new sci-fi comedy series The Orville set to air at 9 pm EST on Thursday evenings this fall, following the fourth season of Gotham.
Certain Gotham season 3 story threads could become all the more important in season 4, depending on how things shake out over the remaining episodes. In addition to the plotline that involves Edward Nygma's (Cory Michael Smith) near-complete transformation into The Riddler and his moves against the Court of Owls, Gotham has taken an important step forward in moving the young Bruce Wayne (David Mazouz) towards becoming the Caped Crusader in the future. There is also the question of whether Barbara Keane (Erin Richards) will become Harley Quinn in the Gotham-verse (as long predicted by fans) and what that means, as far as the potential for a Gotham City Sirens storyline in season 4.
As (briefly) alluded to earlier, Gotham's changes to the conventional Batman comic book mythos has frequently left longtime Caped Crusader fans baffled, if also uncertain and thus all the more intrigued to find exactly where the TV show's story is going next, as a result. Gotham's "loopy" spin on famous Batman supervilains has managed to earn the series a loyal audience both because and in spite of this. Still, as is always the case when a TV series changes its air date during the week, there is the question of whether Gotham's viewership will change (for better or for worse) in season 4, as a direct result of its move to Thursdays.
Gotham continues tonight with ‘Light The Wick’ on FOX.
