Confusing and poorly explained plot

Rating: 6/10 (25 April 2013)

I am a massive Iron Man fan, always have been. I was so excited for this movie and the trailer looked amazing. And the trailer was one of the problems.
The trailer portrays the movie one way, which is unfortunately nothing like the movie. The movie revolves around Tony Stark, and NOT Iron Man, which i was i was expecting to see. He's barely ever in the suit, and even when he is, you're not sure if he really is because of his new technology. The new technology seems over the top and poorly explained.
I don't really know much about the comic book series which left a few gaps in the story. Details were left out, especially regarding the virus.
But the ending was by far my least favourite part of the whole movie. He's no longer Iron Man? How is that even going to work? What is going to happen in Avengers 2? And even if i can get over that stupid ending, if he had the ability to fix himself, why didn't he do it in the first movie? Or when he was almost dying in the second movie and have to make his own element? It makes no sense. He was always a genius and it seems he always had the ability to do that, so why didn't he earlier? Just because of Pepper?
Overall, I didn't hate the movie, but it was nothing like I expected or hoped and was a severe let down after how well The Avengers was done. An average end to the trilogy, definitely my least favourite, but still worth seeing if you're an Iron Man fan.
