Mad Captains of Star Trek Matt Decker in The Doomsday Machine

The Planet Killer is like the shark from jaws, and the episode is like Jaws in some ways. For one thing, they need a bigger boat, the Enterprise is presumably identical to the Constellation, which couldn’t have fared worse against the Planet Killer. Commodore Decker, like Captain Quint, is undeterred and commits everything to destroying his adversary.
