This is the best one so far. The action and stunts are once again taken to a whole new level, with the Burj Khalifa sequence being the obvious but not only standout, and the supporting cast are the best its ever been, with Simon Pegg, Jeremy Renner and Paula Patton all bringing something new to the team whilst never really taking the attention off of the central plot. The plot is decent, the score is really good and Brad Bird brings his own distinctive flair to the franchise. That's a main part of what I love about this franchise - the amount of different directors that have brought their own style to the franchise makes it always feel fresh and different from its predecessors. I have two small complaints, the first being that the villain, whilst menacing, isn't really as good as Phillip Seymour Hoffman in the last film. Secondly, with the best set piece being the Burj Khalifa climb by far, it does make the final action sequence not as impressive given what came before. Overall, though, this is just a great action film, and one I'd definitely recommend.
