As no one comes to buy her, Grumpy, a young cat, feels angry and hates humans, once finds out that a girl is going to buy her, as she likes her the most, the thing that inspires her life.
The best way to describe the film as a whole would be if Bill And Ted's Excellent Adventure, Home Alone, Garfield, icanhascheezburger, product placement, commercial breaks, outdated cultural references, suburban community theater, and acid had a baby.
[It] has some funny lines from Plaza while occasionally inserting Grumpy Cat into ridiculous situations, but is mostly trying to do what it can within the limitations of its budget, its network and its leading feline.
Grumpy Cat's Worst Christmas Ever could use a whole lot more of Plaza's ad-libbed derision for the entire project and the suckers who find themselves watching it. The claws do come out, but the scratches just aren't deep enough.
