Why can't marvel character have a good third movie?

Rating: 8/10 (22 June 2013)

Okay, so we have had a lot of Marvel characters movies already and just a few of them actually got to their third movies. Spider-Man 3 and X-Men: The Last Stand were horrible and with Iron Man 3's trailers and predecessor movies we had a huge hope for that movie. And does the movie pay it back? The answer is a out loud NO. The movie fails in every possible way, the only scene we actually get a bit nervous is when the Mandarin attacks Tony's house, but we have seen this scene in every trailer of the movie. Of course Robert Downey Jr. delivers a perfect job, so does Gwyneth Paltrow and Ben Kingsley. Unfortunately for those last two the script just fails. A lot of people are having problem with the Mandarin and having it as the major complain about the movie. Of course I have a problem with that too, but this is not why I hated this movie, although it helped a bit. Shane Black would have succeed with this idea of a fake terrorist in any other movie, because it's a brilliant idea, but not in an Iron Man movie ans specially not with the most interesting and epic villain of the comics.
Everything in this movie doesn't make any sense when compared to the older ones, like armors that need to be recharge, making the chest reactor almost useless, or the fact that we met the Ten Rings terrorist in the first movie, we even see their symbol on the TV every time the Mandarin shows up, but in the end the Mandarin does not even exist. Don Cheadle is only in this movie because he was in the second one because his character does not make any difference at all in this movie. The villain plan is insanely stupid and not explained and the reason he wants to get back on Tony is just stupid. Also Rebecca Hall character was there just to create the Extremis and then they just waste her, I don't even remember her name. They might just have told us that Aldrich Killiam created it and so she would not even be in the movie, because she was not necessary there.
All in all this is just a huge disappointing movie and I am not even willing to see the next flicks on Marvel characters until The Avengers 2.
