My first reasonable post is the thought of other movies going back and touching up on special FXs like GL did. I was specifically thinking about Ghostbusters

Now Im not a huge GB fan but I do like the movies and I was watching today on CC and I thought to myself, man I wonder if Sony decided to go back and redo all the proton shootings and Mr Staypuft in CGI instead of blue screens. Since it looks like GB3 is coming out, who would know if something like this could happen

What would you guys think of GB went back and did something like this? Would there be fan outcry or would there be open arms with the new special FXs?

Also please mind that I am not a huge fan but I just thought of this and if they actually did touch up any special FXs already in DVD releases or made revisions/alterations, I would love for someone to point them out to me.
