I get fed up with creators and film makers tampering with something that was great. imo, if you have to change the character, don't. Make something new.
One can argue forever whether creators of TV and movie versions of popular characters "should" change everything around. Still, I've never understood why so many adaptations of older characters dump all the attributes that defined them, leaving a totally new character with the same name.
Old time TV and movie people insisted that TV/movie audiences were different from comics audiences and wouldn't accept things like skin-tight costumes and energy blasts. Admittedly, given the small budgets and limited technology available to them, those things would have looked pretty awful. So Captain America turned into Evel Knievel in a funny suit. That's changed a lot now that comics have gone mainstream and comics creators and movie makers are often the same people. Still the impulse to overhaul everything persists.
I can understand the argument in favor of name recognition. Everyone's heard of Superman. More people are likely to go see a movie if its totally-unrecognizable hero is named Superman than if he's called TeethGrittingMan. But why overhaul a character hardly anyone has heard of?
That's what puzzles me about many revivals of public domain Golden Age characters. A team of creators announce a revival of (pulling a name at random) The Red Bee. Then they change the hero's powers, the costume, the supporting cast, the backstory, and the time period. Why even bother calling this a revival? You gain nothing: The Red Bee has no name recognition, no nostalgic fans, no licensing to support. He'd have no better chance for success than if he'd been The Blue Termite.
