If you are a fan of Scooby doo or Halloween you will adore trick or treat Scooby doo! Great animation and some "creepy" moments make it worth watching. Scooby doo and the gang are amazing as always. The monsters are designed really well and the mystery was pretty cute. If you or your kids want to watch something short but fun I'd 100% recommend this movie. P. S. If your interested in some more fun Halloween movies I'd recommend:
-coralline
