Iron Man (2008)
Superbly cast (the baggage Robert Downey Jnr. carries with him works in the films favour) with no-one camping up their performance because it's a superhero movie, Iron Man is a strong first offering from Marvel's film division. The story is kept down to earth and always with an eye on keeping it personal (the bad guys plot has more to do with jealousy than plans for world domination) and the humour mostly character based. It is perhaps just slightly too long and the climatic fight suffers a little from not being able to see what is happening clearly but it ends with the most perfect last line since Casino Royale.
