1) Hocus Pocus 1993
Most people know this one. It's about three witches who get resurrected by a kid named Max. Who doesn't love some cheesy 90s humor?
2) Under Wraps 1997
A mummy, appropriately named Harold, comes back to life when three kids discover him in a creepy house. They end up becoming friends even though Harold can't so much as utter anything more than "ugh". They find out that he needs to be brought back to his coffin by midnight on Halloween, or he will be gone forever!
3) Halloweentown 1998
Most have seen this movie as well. It's basically the standard when it comes to Disney Halloween movies. Marnie finds out that she is a witch from her kooky grandma, even though her mom has been trying to hide it because she wants her to just have a normal life. Marnie and her brother and sister follow her grandma on Halloween to a mysterious bus stop that takes them to Halloweentown, where ghouls, ghosts, and everything creepy are it's inhabitants. Fortunately, there are some nice ones out there! The caveat comes when the Mayor, Kalabar, is actually an evil warlock that tries to turn the town to stone. It's up to Marnie and her family to try and stop him! A must see.
4) Phantom of the Megaplex 2000
This one is about a kid named Pete Riley who loves his job at the movie theater. On a big movie premier night, he's feeling stressed. The owner of the megaplex is supposed to show up, and his manager is putting tons of pressure on him. He has to keep an eye on his younger brother and sister at the theater while his mom is out on a date. Things start going wrong, and it seems there's a strange masked man causing tons of problems, and even ruining movie reels while they are being played! The masked man is revealed at the end in a strange plot twist you've just got to see to believe.
5) Mom's Got a Date with a Vampire 2000
For the year 2000, this movie was ahead of it's time. Vampires interacting with normal people? Say whaat? This movie is about a single mom with three kids that meets a strange and mysterious man whom she ends up going on a date with. However, the youngest kid Taylor thinks that the man is actually a vampire. Long story short, the mom becomes entranced by the man and it's up to the kids, along with the help of a Van Helsing type of dude to help save her! Check it out!
Honorable mentions: The Nightmare Before Christmas, The Tower of Terror, The Poof Point.
So, that's it! Check to see if any of these movies are available through Hulu, Netflix, or something similar. Otherwise, your best bet is to find a DVD online [or vhs tape!?]. Or maybe even try a video rental store like Family Video, because that's still a thing you know.
