Don't get me started on the re-mastering!
Extra bits in I could cope with more. The sort of thing I was massively not impressed with was the edit at the end of Return of the Jedi where they change the 'ghost' of Anakin for Hayden Christiansen instead of the original bloke. Really annoyed me!
Yep... and why do it? They didn't change Obi Wan for his younger self... why do it to Vader?
I won't even mention the 'prequels' as I like to pretend they don't exist.
