The early '60s version of Edgar Allan Poe's story starring Vincent Price was intentionally campy, and came out quite cool. THEY DID NOT NEED TO MAKE THIS HALF-FORMED VERSION!!!!!!! It's not just the stilted acting that's the problem; I'd say that the biggest problem lies in the casting. Martin Landau as Roderick Usher wasn't a bad choice, but did they really think it wise to cast Robert Hays, after everyone remembered him from "Airplane!"?! Or Ray Walston, after everyone remembered him from "My Favorite Martian" (not to mention "Fast Times at Ridgemont High")?! As for Charlene Tilton, I best remember her as one of Jodie Foster's friends in "Freaky Friday". by Lee Eisenberg
This is not the classic Roger Corman/Vincent Price version, and I have read that movie is simply awful, which means it would be perfect Rifftrax fodder.
