The second season, however, was met with a more polarized response, particularly for its narrative, heavy reliance on throwbacks to the original series, and its negative stereotypes regarding bisexual relationships, butch women and transgender people. The Los Angeles Times put particular emphasis on Carrie, the series' first clear butch character who was portrayed as an overweight, self-loathing, insecure woman easily intimidated by Bette (who was described as exhibiting "snooty behavior" with numerous traits consistent with narcissistic personality disorder and emotional insecurity when near both Tina and Carrie), and Finley, who was depicted as overly carefree to the point of being constantly drunk and potentially dangerous to be around. Bree Tomas voiced her defense for the butch community, particularly Rosie O'Donnell, who after being cast as Carrie was subjected to online abuse, fat shaming and negative comparisons to Jennifer Beals on social media by fans of the series, which was widely condemned by critics. According to Showbiz Cheat Sheet, following the airing of the second-season finale, which saw the end of both Bette and Pippa's relationship and Tina and Carrie's engagement due to Bette's actions and behavior, and ended with a cliffhanger that teased a third reunion between Bette and Tina, fans expressed their displeasure with Bette and Tina's storyline, labelling it as too repetitive and "out of line", and took to Twitter with the hashtag "IleneSavetheLWord". Ilene Chaiken, the creator and showrunner of the original series who herself had come under heavy criticism for reinforcing negative lesbian stereotypes, responded by praising Ryan's work and defending her decision to give Ryan full creative control.
Season 3 was met with an overwhelmingly negative reception. Following the airing of the second episode, which saw Bette and Tina's third and final reunion, Ryan gave an interview regarding Bette and Tina's relationship. Though Ryan had previously stated during the first season that she wanted to take storylines in different directions, Ryan recanted her statement in the interview and said that her intention had always been to build up towards a wedding between Bette and Tina, revealing that following the first season and the revelation of Tina's engagement to Carrie and Bette's dinner date with Maya, she was harassed with direct messages on social media demanding that she reunite Bette and Tina "or else". The interview was met with both praise and backlash from fans, with some accusing Ryan of lying and deliberately choosing predictable and unrealistic fan service over creativity, and comparing the one year time skip between the second and third seasons to that between Star Wars: The Last Jedi and Star Wars: The Rise of Skywalker which left numerous season 2 cliffhangers unresolved, such as Dani's arrest and Tom's planned proposal to Alice, and the circumstances of Bette and Tina's renewed friendship unexplained other than Bette going offscreen on another buddhist retreat and claiming to have changed for good, which was met with harsh criticism and accusations of downplaying Bette's behavior and its effects on her relationship with Tina. Fans were also critical of Pippa Pascal's role in the overall story, with some accusing Ryan of using Pippa, Bette's first serious African-American lover, merely as a token to change Bette's personality and make her more compatible with the Caucasian Tina, a decision which was perceived as racist, and Pippa's subsequent appearance at Bette and Tina's wedding was brought under question. The unresolved fates of Gigi and Tess were also met with criticism, and Bette and Tina's wedding was described as "anticlimactic" and "forced", given that Bette and Tina received far less screen time than the wedding guests. The return of past characters such as Max Sweeney, Tasha Williams and Dana Fairbanks, however, was met with some praise, with particular focus given to Max, who was depicted as being in a relationship with a fellow trans character and raising four children, and his interactions with Micah were cited as one of the season's highlights.
