I . . . I actually don't know what made me think of this again, but . . .
So, almost ten years ago, I found this Film School 101 production on YouTube called WONDERBANG ISLAND. Now, this was supposed to be an homage to H.R. PUFNSTUF, with a "what-if" scenario involving Jimmy having grown up on the island and becoming fed up with all of the zaniness around him. Now . . . ehh . . . the characters and the suits and all are actually rather well-done for a no-budget film school project, and the scenery and everything is very much Krofft-like, so I give it A for effort for that . . . but the story . . . the story is just so . . . it's so disturbing and kind of dark, that it makes the whole film seem all the more creepy when factoring the Krofft-like atmosphere into the equation, which somehow doesn't even help the story.
So, if you think you can stomach it, here it is - and IMHO, part 1 starts off okay, parts 2 and 3 get darker and more disturbing, and part 4 is just downright depressing. Oh, and caution: there's a couple of racist caricature characters, a strongly implied rape scene, a tries-to-be-graphic depiction of a diseased baby dying, and defacation. . . . All wrapped in a Krofft homage:
