A nice movie which gives us the feeling that every mystery that Mystery Inc. tries to solve is better than the last one. The characters are as funny as ever, and the fact of the Hex Girls making their debut in the Scooby-Doo series, makes this one of those movies we Scooby-Doo fans cannot miss. The plot itself is very well written and thought, because we find out that not everything is what it seems, and we get to face a fake witch and a real witch who wants revenge on those who imprisoned her.
The voice cast is really good, and we get a really great time from laughing about the characters and the situations they get themselves into. A great movie with a great mystery. Don't miss it!
