More than 3. Every re-release had some changes made to it thus making them less and less "original" every time. What people would try and find on the internet and what Disney is releasing now is basically what was shown in theators when the movies came out. Lucas never wanted anyone to have those and decided he wasn't "satisfied" with them so he proceeded to change them continuously.

No. The original movies which were shown in theators have been altered a bunch! They have replaced the original SFX with crappy CGI that looks out of place, have changed the things characters say, and have even changed some of the events which have happened. The fans want the original movies, not something which is constantly being slightly altered and changed. Example of one would be Han shooting first in the original movie but Lucas changed it to Greedo shooting first. May not seem like much, but if you delve deep into what defines Han as a character (ie. outlaw) you would realize how important it really is. Imagine if Da Vinci came back from the dead and decided he wanted to give the Mona Lisa a makeover... You really think we would let him? Basically, the remakes dont maintain the character that is Star Wars itself. They feel changed and unoriginal. They are not the same movies people saw in their childhood. Don't be mad at Disney for giving the fans what they have wanted. Be mad at Lucas for ruining his own masterpiece despite the fact that no one wanted that.
