This series is great. Some of the episodes are just made up out of the blue, while some are similar to classic horror films such as Nightmare On Elm Street, The Picture of Dorian Gray, etc.. But don't worry, all of them are kid-friendly ;) (other than the violence). There is no gore whatsoever.
Some episodes are more scary than the rest. Some of the scary ones are: Dreamcatcher, Headshot, Lovercraft's Woods, Really You, The Return of Lily D., Pumpkinhead, Return of the Pumpkinheads, The Girl in the Painting, Near Mint Condition, etc.. The episodes that are "scary" aren't that scary, they're just scary in accordance with the other episodes. It depends how young your kid is.
This series teaches life lessons. For example,the episode A Creature Was Stirring teaches you that you should appreciate your family because a disaster can happen at any moment and to be careful what you wish for.
I highly recommend this series to everyone that likes scary stuff that isn't too scary.
(Also, this series has been discontinued but you can find tons of free older episodes if you go on youtube and search in: "thh". Thh stands for the haunting hour. Once you search that in, tons of episodes will appear from the youtuber: "Spooky Scary Shows!". You're welcome. ;D)
