Scooby-Doo! Shaggy's Showdown

So Scooby and the gang are in for Norville Roger's (a.k.a Shaggy Roger's) great great ancestor in the great wild west . Shaggy comes across his cousins . So the mystery revolves around it . Shaggy's ancestor's dead so who's impersonating him and misusing his name for the loots is what the story's about . I personally didn't like this film cause it just doesn't flavor up to the expectations . Having a ghost rider shootin about . Something better could've sufficed . The main thing with the Scoob movies is that the horror, mystery along with the comedy should click and work . If the horror's lame and ridiculous then the comedy should save the film . If both don't then it turns out as a flop.
