- Angst? What Angst?: Donna's death happened six months before the season two premiere, was mentioned in passing at the beginning of said episode and was barely brought up again.
- Harsher in Hindsight: During one of the interviews on the subject, Kevin James defended killing off Donna on the grounds that the show was running out of ideas and explicitly said he'd doubt they'd get through a third season without this shake-up. The show was cancelled after Season 2.
- Never Live It Down: Since Donna was written out to bring in Kevin James' old The King of Queens co-star, the second season was dogged by joking suggestions over how else to "improve" the show, such as Kevin becoming a delivery man or a character played by Jerry Stiller moving into the basement.
- Overshadowed by Controversy: These days whenever Kevin Can Wait is discussed, it's likely to bring up how CBS botched the second season so badly.
- Replacement Scrappy: Vanessa who replaced Donna as the female lead for Season 2 after Erinn Hayes' firing. This especially considering Donna was written out to make room. It's now looked on as one of the major catalysts as why the show was not renewed for a third season.
- Seasonal Rot: The second season where Donna was killed off, Vanessa was shoehorned in to play up the nostalgia from King of Queens, Kevin Took a Level in Dumbass and the show relied more on Cringe Comedy.
YMMV / Kevin Can Wait
