a good, decent guy, kind of goofy, tries to do the right thing, in love with someone who doesn't love him back, but strong enough to face up to that in the end, starts off watching the game on telly and goes on to save the world with the skills he taught himself

Your characterization of Mickey is nothing short of awesome. I think you summed up, in one sentence, what made me turn from not liking the character/feeling sorry for him to completely loving him and wanting more.
