I'm in a dilemma: I don't want my characters to have flawless, limitless and bad-consequence-less powers, but I also don't want to have my creativity limited by such rules and limits.
In my case, it's not a book, but a multimedia work, i.e. such powers are visible, with flashy effects and all, instead of just imaginable, so the possibilities are different from books.
I find it awesome when I see a work where the creator has the freedom to make the character use a new power out of nowhere, usually a character whose powers are not much explained (or even well explained, but in an unexplainable/incoherent way they manage to do that) and most of the public just don't care about how the character found out that he could do that, or that doing movement X would result in such new power, or why it happened, no, they just like it, because it's cool, if it's cool, screw logic, it's cool!
I want to have creative freedom to create the powers, but I don't want to keep the questions above unanswered. However, the more I explain the whys and hows, the less freedom I have, and the more I try to fix things up, the more incoherence is created.
Now how to resolve this dilemma? Do I keep all the rules and sacrifice "coolness" for the sake of coherence/realism, or do I surrender to the "Rule of Cool"?
