I prefer the original originals

The only change which was really necessary was the Jabba change. In the original version of IV, Jabba was just a regular guy, and then he suddenly turns into a massive slug in VI. It didn't make any sense, so I like that they edited IV to make Jabba a slug.
They only talked about Jabba in the original New Hope and The Empire Strikes Back. The scene with him and Han wasn't in the film.
