- Alternative Character Interpretation: Carl in the season five finale. Total jerkass, or someone who was hurt that his best friend took the side of his ex (who did not want to marry him at all anyway) and her family? Note that even Mike agreed that he was a big part of his being with Molly in the first place, and did want him there at the anniversary party, since it was his idea. Heck, Mike never really defended him, and did not suggest to Molly that neither Carl or Victoria should be invited, allowing for a situation where someone will be hurt and lash out. However, his reaction to end his friendship supports the former interpretation.
- Apple of Discord: The Flynn house has a minimum of three bathrooms (upstairs, main level, and basement), yet access to a bathroom is frequently argued about as though the upstairs bathroom is the only one.
- Ensemble Dark Horse: Peggy, Mike's mother, steals the show whenever she's on and gets increasing amounts of screen time as other characters, like Molly's family, get less focus or put on a bus without explanation, like Carl's Nana.
- Vince seems like he would've been a short term character when he first appeared, but quickly became a regular.
- Fridge Brilliance: Victoria's perpetually-stoned state, constant sexual indiscretions and partying could be shrugged off as irresponsible behavior that she will never grow out of... until you realize that they're more likely coping mechanisms she clings to because she does the funerary make-up on corpses. Self-defeating or not, she holds down a job and can be there when her family needs her. That's not usually indicative of a self-absorbed Hard-Drinking Party Girl with a side of drug addiction.
- When Frannie runs off in "Baby, Please Don't Go", Mike immediately finds her right where Molly originally ran into her. Obviously, he's better trained to find her due to being a police officer. But Frannie knew he was a cop, so why did she go back somewhere she could easily be found? Because she thought that Mike wouldn't want to find her.
- Hollywood Homely / Hollywood Pudgy:
- The show could be the ultimate aversion of both these tropes. Mike and Molly actually look like two people who would be at an OA meeting. And despite her weight, Molly is considered to be rather lovely both in and out of universe.
- Inverted by Victoria. The actress that portrays her is not excessively thin, but she is portrayed as a sexpot and no mention is made of her weight.
- Ho Yay: Mike and Carl, big time.Mike: Why is it that at least three times per week someone thinks we're gay?
- Jerkass Woobie: Peggy. She is a pretty mean Deadpan Snarker and guilt-tripper, but seems to be quite lonely. As of "Whatever Happened to Baby Peggy," we find out she's the victim of Abusive Parents , and for once it's not Played for Laughs.
- Seasonal Rot: The consensus for a bit of season 4 and season 5. The show capitalizes on Melissa McCarthy's popularity, but overuses her to death, changes her character's behavior radically, and takes away much of the focus on the relationship between Mike and Molly.
- Averted in Season 6, as the showrunners went back to the formula of the first three seasons, focusing on the family and wrapping up the long aborted baby arc.
- Spiritual Successor: To The King of Queens.
YMMV / Mike & Molly
