I watched this movie knowing how much of a chance it had to be awful. The most recent Disney Channel original movies have been complete crap (case and point, The Cheetah Girls). And this movie is the third of two great movies already, and I was shocked to find that it was actually good! The only complaint I have is that there is no mention of Cal or Calabar, the villains from the first two. The story starts out with Marnie (Kimberly J. Brown) and her grandmother Aggie (Debbie Reynolds) are planning to bring kids from Halloweentown, disguise them as humans and have them attend a high school in the mortal world, to prove monsters that live in Halloweentown aren't dangerous. But of course, there is a problem, if Marnie can't prove to the humans that the monsters are harmless, she, and her family will lose all their powers.
When the monsters start attending the school, they all stick together and aren't interacting with their fellow human schoolmates, so Marnie suggests they do different extra curricular activities. Then, they start making friends. Then, they sign up to make a haunted house for their school Halloween Carnival, but they make it so it is a wax museum with wax monsters sitting, drinking tea, and eating cookies trying to how that monsters mean no harm. No kid at their school is amused by this. And during this whole time, the monsters are being chased down by evil knights, which leads to a surprising revelation. This Disney Channel movie has surprisingly good computer special effects. Considering their latest effects-laden original movie, Zenon: Z3, had the worst computer effects I've ever seen. Another thing great about this movie is that Disney seems to have a knack for getting the same actors back for their sequels to their original movies. Kimberly J. Brown, Debbie Reynolds, Judith Hoag, Joey Zimmerman, and Emily Roeske are all back, and have been in all three Halloweentown movies. If you haven't seen the original Halloweentown movie and its sequel, I would see those first, because there are some things that might not make sense. You have to see them in order to get the entire story. All in all, this is the best original movie Disney Channel has produced in quite a while. 9/10
