Quite frankly, I prefer the non-CGI stuff that's in the movies, since a lot of times the CGI that's in movies tends to look rushed and just doesn't hold up to real models. Real models just tend to add a depth of dimension to the movies that CGI tends to lack.
So fix up the scenes with real models then!
If they want to keep repackaging the same 3 movies over and over again, at the least fix the stuff that was wrong with them.
I buy blu rays for higher definition, and not because they fucked with the originals.
