Ahh...Disney Channel original movies. This particular one falls into the category of (and every adult male who has seen "The Notebook" can relate to me on this) "movies my girlfriend made me watch." The second in the four-film Halloweentown franchise, this is by far the darkest and most serious (and therefore, probably the best.)
The series follows the Cromwell family of witches who live in the real world under the guise of being normal people. But, as always happens when Disney wants to make a sequel to their franchise, end up entangled in the sordid affairs of Halloweentown, a world where various ghouls and monsters live together in peace and harmony.
In this installment, an evil warlock seeks to doom Halloweentown to become a drab and monotonous world while turning humans permanently into the monsters that they dress as for Halloween. After a few bumps in the road, protagonist Marnie and her witch family save the day and everyone lives happily ever after (until the next sequel!)
Festive, fun, and with very little need to think (though I do applaud the filmmakers for at least attempting to explain the wackiness with Stephen Hawking references) it's a perfectly fun waste of time for the Halloween season. It's a Disney Channel movie, after all! (Interestingly, it was directed by Mary Lambert, who directed the Pet Cemetary movies, no doubt accounting for some of the quality.)
Honestly (and I'm sorry to let the cat out of the bag on this one, guys) I end up liking most of the movies my girlfriend makes me watch anyway.
