7. Demon In A Bottle
Marvel tackling Tony Stark's alcoholism was always unlikely, but they should have left it completely off the table rather than the watered down version we got in Iron Man 2. The hero getting tipsy and wrecking his house made him look more like a fool than someone struggling with a very real problem, and his drinking quickly vanished when the sequel moved on to the next plot thread in a movie which already had far too many of them. However, Iron Man 2 took many other elements from Demon in a Bottle and completely messed them up. Perhaps the best example of that is what it did with Justin Hammer. Portrayed as a jokey loser instead of the man who destroyed everything in Tony's life in the comics, Sam Rockwell was completely wasted, but did do the best with what he had. With no Iron Man 4 in sight, this story being done justice may never happen!
