There's change, and then there is CHANGE. What people want is to take the 7 ingredients of the original, remove 2 and add 2 new ones. What they don't want is to remove 5 ingredients and add 5 new ones.
Nothing wrong with that, if the new ingredients are good. "Change" as an abstract category is neither good nor bad. What matters are the specific changes and whether they're worthwhile in their own right. I mean, the Bixby/Ferrigno Incredible Hulk series changed almost everything from the comics, even the protagonist's first name, and it still turned out pretty terrific. The Mission: Impossible movie series has only a tenuous relation to the TV series, featuring different characters and turning what was originally a meticulous heist/caper procedural into a huge action franchise, but aside from the first two, it's a pretty darn good series of action movies. The CW's Charmed remake kept the broad premise but used new characters and changed a lot of the worldbulding, but I actually thought it was better than the original. Indeed, The CW has done other "same general concept but different characters" remakes that I thought worked pretty well, including 4400 and Kung Fu (which barely even has a concept in common with the original).
