I think that perhaps the undoing of Jaws III (1983) comes with its gimmick. This was supposed to be its drawing lure. Come see the great white shark in 3-D!!! That scene at the end where Jaws bursts through the control room window, threatening our heroes, the shattering glass couldn't look less effective. In fact, it carries the unfortunate label of "cheesy", certainly not the intent of the visual effects folks. Jaws does munch down on one of Gossett's control room tech operators. Chomp, chomp! So there was that. Oh, and what about those heroic dolphins!
