S01-E08 of a revamped "Scooby-Doo" cartoon series, with two seasons worth of episodes running a seat-numbing 60mns and featuring a roster of guest stars. Here, it's Sonny and Cher's turn to team up with the kid detectives while the whole gang is stranded on the sea-engulfed land of a dilapidated hotel, one supposedly haunted by the ghost of a Shark God. But never mind all that, how are Sonny and Cher when performing their own voiceovers? They don't sing (a missed opportunity), also Cher is drawn poorly--and she keeps referring to herself as an "old wife" or an "old woman"! However, some of the familiar S&C banter, derived from their TV show, has a little snap. Still, it took 13 writers to come up with this teleplay, one that doesn't even allow Scooby-Doo anything funny to do.
