Sooo glad people aren't forgetting about Kang. Though Ultron could offer a more dynamic villain storyline with his knowledge of technology, and our reliance on it. He could do anything from crashing planes, and hacking agencies, to building a robotic army, and turning every techmological device on earth into a weapon. The possibilities are endless story wise. He's much more fitting for this time period. Kang may be a bit too similar to Thanos to casuals. I do love Kang though, he should definitely be in guardians of the galaxy 2 or 3.
