Currently available on Netflix Watch Now for streaming players, it's a modern Scooby Doo adventure. If you're thinking of Scooby, you probably know what to expect. Some violence, light inappropriate language (like stupid, etc.) and mildly negative role models. This movie mostly stars Scooby and Shaggy in a Halloween Adventure. My 5-year-old has watched it without much concern, and it has some genuinely funny parts. The scariest part involves the Headless Horseman, but it's lightened up with a few jokes (and a jack-o-lantern voiced by Jay Leno).
