The guy over youtube say about CED:
The audio quality is phenomenal just like listening to a record.
MM1 BluRay, the colors are too cold, that is not Australia, it’s only modern look.
My ratings:
MM1 - Masterpiece
MM2 3/5 - Characters are excellent but I don’t like story.
MM3 2/5 - Uff
New MM 1/5 - They can add any kind of CGI, stuntmens can makes miracles but story is awful. TRASH
