Seaquest The early 90's series set in the near future on a large Deep Sea Vehicle (DSV) starter out as a mostly science exploration show with some political overtones. Year two removed many cast members and replaced them with younger actors to appeal to it's target demographic. The show pushed for more SciFi and fantasy elements in story. Even more cast changes, and a new title Seaquest 2032, in the third year as most of the actors were very unhappy with the new approach in the show. The ship leaves the Earth to fight on another world and is almost destroyed. Then turns up 10 years later back on Earth and picks up a new Captain. The show went back to a more straight laced adventure show, but was cancelled mid season.
