But can Khan work as a villain in a two hour movie? Tricky. He will be starting from zero since his backstory is "bad guy frim Eugenics Wars" and that's it. The audience needs to be told: What is the Eugenics Wars? What was Khan's role in it? Why do the charatcers care about this part of their history? Why should the audience care? And by the tme you've gotten through all that blahblahblah, the audience is bored and has gone to the lobby for popcorn.
They managed to explain Khan's background in Space Seed in about one minute and a half, so why wouldn't it work in a movie?
Every character in every given movie has a certain backstory that is important for the respective movie, I don't see what the problem is here. Even if the villain in XII was a completely new character, he would still have a backstory that needed to be explained.
The Enterprise crew has already been introduced in the last movie, so they have even more time now to introduce whatever character they've chosen to put into the movie.
