- Broken Base: The constant fourth wall breaks and Biting-the-Hand Humor. Funny additions that make the film have a more unique personality, or just a demonstration of how little effort was put into the movie?
- Grumpy Cat's personality is also this. While most agree that the Deadpan Snarker characterization was accurate to the character, there were debates over whether Grumpy Cat was all that, well, grumpy. Some feel that the character needed a wider range of emotions to fill an entire movie, while others felt her grumpiness was too downplayed and thus removed her one distinguishing personality aspect.
- Idiot Plot: At its own expense, the film frames its own narrative as an example. Lampshaded as Grumpy Cat herself notes that if she and Crystal would have done the simple and obvious thing and gone to the police right away, there would be no movie. Even when Crystal does get access to a cell phone, she calls her confused mom instead of 9-1-1 in order for the third act to have an obligatory chase scene. The villains aren't exactly the brightest bulbs either, frequently enduring providentially contrived and wholly avoidable setbacks.
- Romantic Plot Tumor: The relationship between Crystal's mom and a guy who works as a mall elf is accused of being this when Grumpy lampshades it by calling it a boring B plot.
- So Bad, It's Good: Invoked. The movie is very corny and campy, and that adds to its charm. Grumpy's snarky attitude about the corniness also helps.
- Took the Bad Film Seriously: Daniel Roebuck as the security guard George, in sharp contrast to the Ham and Cheese stylings of every other character, actually puts in a pretty decent performance. His reveal to be the true Big Bad is surprisingly effective, as he plays both his fake goofy personality and his true Faux Affably Evil persona perfectly to where he's genuinely unnerving.
- Tear Jerker: A meta example when Tardar Sauce (a.k.a. Grumpy Cat) passed away on May 14, 2019.
