The whole point of having great characters is the opportunity to explore them more deeply with time, re-interpreting them for each new age.
I'm sorry, but anyone who thinks the use of an angelic (or seemingly angelic character), whose likes have been written about for, oh, about 4,000 years, is ripping off Star Trek, has his head so thoroughly up his ass as to have blipped into an entirely new intestinally-based reality and desperately needs to get a wider frame of reference.
When the Seinfeld show said it was going to be a show about nothing, everybody said it couldn't - wouldn't work. It did. Thor is about something, about that character finding his destiny, but it's not doing what was expected... and yet it's doing very well.
All you can do is focus on telling the best story you can with compelling characters. If you do it right, it will endure. If you do it wrong, it won't.
I can easily come up with ten really iconic stories/trade paperbacks for Superman, Batman, others... name me ten equally big, iconic Wonder Woman stories. Much harder. That ain't the character's fault, that isn't sexism, that's just not servicing the character.
I keep waiting for a paradigm shift to happen that will let network and studio execs see that sci-fi is the same as any other genre in terms of how you approach it - logically, character-based, with challenging ideas and forward thinking - but I worry that it might never happen in my lifetime.
The only thing that I discovered very early on is that, even though we might change schools and cities and towns and states, the books in the library were the same. They had the same covers. They had the same characters. I could go and visit those people in the library as if I knew them.
When writers don't know what to do with a character, they build up the supporting cast and universe to kind of hide that fact. After a while, you can no longer see the character for the underbrush. When that happens, you need to bring out the weed-whacker to clear some of that away so you can focus on the main character.
Coming from TV and film, rule number one is that you always service the main character first and foremost. If that's not working, you've got nothing.
