5. Much, Much More Hulk
Why It Sucked: Well both Bruce Banner and his alter ego were the most interesting characters in this film, however no-one seemed to realise that. Bruce Banner was the only character who developed, who had complications and things he had to handle and he was also the one people seemed to not care about until he went all bad-ass and green. Its a shame really; they finally did The Hulk properly but then missed out on the opportunity to make him the complete focal point. Every scene he had a chance to flourish Robert Downey Jr was there to overpower him with terrible jokes and awkward nerd banter which just makes us wish we were watching The Big Bang Theory.
How To Make It Better: Have a storyline which relies on Bruce Banner and The Hulks inclusion, rather than just something to complete the get together, Mark Ruffalo was the standout actor of The Avengers and deserves the spotlight in the sequel. Everyone else is just puny in comparison.
