I've never understood why people say that. How can something new possibly change or "tarnish" something that already exists. The quality of the original and/or preceeding works don't change a bit, so what's the deal?
Well look at how the Star Wars prequels change the entire perception of Darth Vader. When you watched the originals from 1977 to 1997, Vader had an enigma of mystery. He was scary, chilling and someone to be feared.
Now you look at him and you try to reconcile how awesome he is in the originals with how bad he's portayed in the prequels by Hayden Christensen. The guy who mercilessly snaps necks in 1977 apparently was a whiny brat who romanced women by comparing their smooth skin to rough desert sand. Plus, don't get me started on the whole "NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO" scene.
Every time I fire up the original 1977 version of Star Wars, there's a part of me that has to say, "Ok, now imagine parts 1-3 don't exist." You can't really escape it.
In Raiders of the Lost Ark, Indy's this no-nonsense adventurer that essentially is so pissed at one point he throws a guy through a truck window before kicking the gearshift up a notch in order to better run the SOB over.
I don't want to have to watch a 5th installment in the future knowing that before going off to find some lost treasure, Shia's got to first swing by the old-age home to pick him up.
Inevitable lines like, "I'll save you dad" would just put a sad note of finality on a once proud series.
