I enjoyed this very episode very much, just like most of the other Twilight Zone episodes. Things that I liked were: horror movies, monster masks, cemetery and supernatural powers.
This kind of story has already been done in other movies I have seen. A monster moves next door or to the neighborhood and the kids either destroy it or become friends with it. The ending here as usual has a twist which was not that very clear or exciting at all, actually I hated it.
Overall a good experience although if it weren't for the monster' subject this would have been a very bad episode for me.
