- Base-Breaking Character: Many of the supporting characters of the show for various different reasons:
- Kevin, Cheesy, and some of the other kids are either funny because of what knuckleheads they can be, or blatantly annoying Hollywood Nerd stereotypes.
- Officer Dangus is a clear example of Police are Useless, but depending on your overall opinion of police in general, that example is either a funny or disrespectful one.
- Broken Base:
- Because so many people remember the '80s series so fondly, this one is a bit of a tough pill to swallow, with some people finding it a perfect continuation of the old show and others regarding it as a bastardization. Especially regarding the character designs. Some criticize the character designs for making the chipmunks resemble humans too closely; others find the designs to be cute and consider the old '80s look to be more human than the designs in this series.
- Cutting out the opening theme's second verse has met with a mixed reaction from both critics and longtime fans of the franchise, though some are admittedly impressed that they kept the original theme song at all (given modern-day remakes' track record of completely replacing them).
- Replacement Scrappy: Ms. Croner serves as this for fans of Miss Miller, who has become a background character in this series.
- The Scrappy: Miss Smith has an annoyingly shrilly voice, often screams like a banshee, and sometimes even goes out of her way to be unnecesarily harsh on the students, particularly Alvin (even in cases where he doesn't bring it on himself as he usually does).
- Tainted by the Preview: From the moment the character redesigns were revealed, fans were upset.
- Uncanny Valley: The redesigned characters look more human than chipmunk now, particularly their noses. When Stu Shostak had animation historian Jerry Beck on one of his podcasts, he commented how a preview for the series on the classic The Alvin Show Blu-ray horrified and repulsed him.
- The Woobie: The poor little Tasmanian devil who gets mistaken for Alvin in "Who's the Animal", who needs an appendix surgery. Fortunately, it turns into a Heartwarming Moment at the end, when he turns out OK and everything is back to normal.
YMMV / ALVINNN!!! and the Chipmunks
