As a result, I looked, I was glad with all my heart and made an inspired conclusion - the potential of "Iron Man" on the whole scale resulted in the second part in an excellent entertaining blockbuster and one of the best comic book adaptations that I saw.
But let's start with the laws of sequels, or rather not from laws (after all, they are not always fulfilled in the production of film products), but from the expectations of the audience: from the second part we expect even more scope, more humor, more battles, more heroes than in the original - and "Iron Man" all these expectations justified.
In addition, he gave an occasion to be stunned by characters with Russian roots - how nice it was to hear that China, Korea, Iran for another 10 years will not reach the technology of Tony Stark (and the competing American company "Hammer" - all 20), and Russian, well and let the villain on the film, Ivan Vanko in the handicraft conditions did not worse, and even made so much noise!
Now back to the original - remember all that you liked the first "Iron Man" - so all this you will find in the sequel, only in places you need to multiply by 2 - and above all it concerns characters.
Tony Stark did not change from the first picture and remained an amazing combination of playboy / genius / showman - so Robert Downey Jr. did not disappoint and gave out the same standing image, maybe even with some deeper into the inner world of the hero (again he does not everything is smooth with health, yes, even here my father was attached).
Gwyneth Paltrow gave exactly the same image, exactly the same - no more, no less.
For a couple of moments, that is, a couple of appearances on the screen pleased Nick Fury in the performance of Samuel L. Jackson, although there is no need to expect any action from him.
Tony Stark's best friend changed face - in the original played Terrence Howard, and now Don Cheadle - but I somehow did not notice the difference (probably because the first part looked a long time and the character there was not the most important place), but he had to act much more - including in the suit of an iron man.
Mickey Rourke portrayed a gifted mind, a hatred for the Stark family and a bunch of tattoos of the villain Ivan Vanko (in the comics - Whip), as it is required from comics, that is, beyond the PG-13 with any profanity or something did not come out, but the image was on the whole turned out worthwhile.
Scarlett Johansson was beautiful and with dark hair, but her character presented a couple of surprises - first of all, I repeat: I did not expect such an image (or I interrupt memories from memories) - so as not to spoil, I will not describe all this, but in the course of the picture, all expectations around her character were covered with a copper basin, although what happened turned out to be different, but not bad at all - a couple of spectacular appearances in the course of the film, to finally shine in the finale.
Sam Rockwell - did not even know that he was playing here - I can not really single out his character - Justin Hammer - the head of a competing company (primarily because Tony, as it should be, was simply eclipsed), but the actor did everything that was required of him.
Final - this is generally a separate merit - the ending of the original and next to it was not compared with the large-scale, spectacular and numerous finale of the second part. Bravo for such a brilliant finishing touch! Although neither the beginning nor the middle was disappointed - another brilliant combination of Tony Stark's humor, an excursion into his rampant life, a fight scene in the beginning and the middle as a foretaste of a much more significant and multifaceted final fight.
Result: the first "Iron Man" was remembered by the bright, but classic manner of adaptations of comic strips with the appropriate filling in the plot plan, which allowed him to become not a breakthrough, but the primacy of traditions and a worthy spectacle for entertainers in general and comics in particular - and the second part from the original in no way fell behind, and in many ways even surpassed him.
