9. The Consultant
In fairness to Marvel, the fact that they devoted a short movie to fixing a continuity error shows just how much they care about making stuff like this right for the fans who dissect their releases. However, a mistake is a mistake, and this one is worth pointing out just as an example of how directionless Marvel were before Joss Whedon saved the day. In the early days, Tony Stark was transformed from someone who S.H.I.E.L.D. clearly envisioned as a key member of the "Avengers Initiative" to a fool they wanted nowhere near the team. Revealing that he was sent to see General Ross not to discuss taking down the Hulk, but to instead just annoy the guy into doing what S.H.I.E.L.D. wanted in the short film The Consultant was the solution. Ultimately, it was also a pretty weak explanation. After his actions in New York, are you really supposed to believe that the World Security Council are daft enough to want Abomination in The Avengers? There are other issues too, and as good as it was of Marvel to address the problem with The Incredible Hulk's mid-credits scene, it just ends up feeling forced.
