I watched the movie The Flinstones Meet Rockula And Frankenstone. This movie has the voice talent of Mel Blanc (Looney Tunes Cartoons), Henry Corden (The Busy World Of Richard Scarry), and Don Messick (The Jetsons).
The Flintstones and Rubbles win a trip on "Make a Deal or Don't" to Count Rockula's castle in Rocksylvania where they have an unpleasant meeting with the Count and his servant Frankenstone.
I give this movie 4 out of 5 stars.
