I dislike much in ROTJ, the post-Raiders Indy films, the SEs and the PT but there are things in all of them that I do like and they are culturally significant.

If the original versions of the films were preserved and presented these sequels, prequels and alternate takes wouldn't be a problem.

Some people wouldn't be interested or not like them at all but to other people they would be interesting curios at least and to some people they would be their preferred versions or as continuations of the original hit their preferred episode in the film series.

It's the scrubbing of the original films from public view and exhibition which is the act of cultural vandalism not the altered versions and spin offs themselves.

CGI is a tool, if it's used correctly it can be a powerful means of getting otherwise impossible story elements onto the screen.

If used badly it can suck the life out of a film and shatter the illusion of being inside the story (as opposed to being inside a theatre or a living room) but the same is true of a terrible optical composite of a physical set, a matte painting (painted with paint) a physical model and live action.

In Temple Of Doom the whole last act is ruined by terrible special effects and none of them are CGI but as a cultural significant film I have no problem with anyone trying to fix the effects (even using CGI if it works) as long as the original version of the film is still available.
