Dueling Shows: With The Loud House, another show dealing with the adventures of a middle child in a big family. This lead to the show's downfall, as the show constantly lost in ratings to The Loud House, with the ratings of Stuck In The Middle dwindling as time went on.
Hostility on the Set: Jenna Ortega and Ronni Hawk reportedly disliked each other immensely with Ortega alleging that Hawk made racist comments about Mexican people, despite playing a character of Mexican descent, and Hawk having openly been a supporter of then US President Donald Trump and supporting his infamous plan to build a wall between the US and Mexico and Hawk claiming Ortega bullied her. While Hawk later apologized for her support of Trump, she hasn't eased up on her dislike of Ortega and the two show no signs of making up. Kayla Maisonet and Isaak Presley both also supported Ortega against Hawk, implying they had similar issues with her.
