I don't know about debate and stuff but "Song of the South" is not getting the DVD release it should. In fact, it has never been released. Ever. On any format.

I also hear people bitch about "Blade Runner," but considering I've only seen it once, I can't remember what they were complaining about.

CGI insertion is a relativly new thing and as time progresses and film directors become old and more delusional there is bound to be more tampering. We are just seeing the first signs of this now.
