“Mariah Carey’s All I Want For Christmas Is You” (** out of four) was a pleasant but forgettable animated trifle about a young girl named Mariah (voiced by both Breanna Yde and Mariah Carey) who dreams of buying a dog for Christmas after seeing a local puppy named Princess at the local pet store and she is then tasked with dog-sitting her uncle’s crazy dog Jack to see if she is ready for the responsibility. Die-hard Mariah Carey fans and very young kids may like this but it’s mediocre at best. This is obviously made as a holiday cash-in on Mariah Carey’s Christmas themed song but other Carey song titles “Languishing”, “The Impossible”, and “Faded” are more apt descriptions of your probable response to this movie.
