While it’s pretty commonplace for films to be re-edited before home video release these days, few have had edits so substantial that they change the character and quality of the entire film as dramatically as the Star Wars original trilogy.
The closest I can think of is the Director’s Cut of Cinema Paradiso, which adds 49 minutes of material to a classic Award-winning bittersweet nostalgia film to turn it into a fairly cringeworthy stalker fantasy film. Not quite as ugly a transition as the Special Editions, but pretty darn close. Also, the original cut of Cinema Paradiso is not suppressed, which means the only problem is the market confusion of having two very different films being marketed under the same name.
