This thread reminds me of the old "bring up all the horrible biased stuff [insert character] did" threads. Those went places. I imagine this thread will too.
he's cool because he's not cool.
How to make Cyclops cool? Have him do something interesting without blaming the interesting action on other characters or killing off better characters so that Cyclops can pout about them. I mean, that would make the character tolerable, at the least.
He is turning into Big Boss Cyclops in a few moths, so maybe Marvel is taking the steps to make him "cool"

I feel like the question poses the belief that Cyclops is "uncool" and boring. I don't feel that way. In fact, I think he's fine the way he is. His current characterization is quite flushed out and allows for interesting interactions with characters like Wolverine. I feel like respectable exposure in a movie would probably work best in improving the character's reception to a larger audience. As he currently is in the Fox films, he is the guy in the way of Wolverine uniting with Jean.

He needs a solo adventure in a mini, introducing a recurring jobber villain that's his alone.
