Almost one of the best - almost!
It captures well the spirit of 1940's America and engages from the start. Hugo Weaving is excellent as Red Skull, or Herr Schmitt, nice pun btw. (Matrix reference). The special effects are quality and the acting top notch. The storyline is mainly one of introduction, obviously preparing the ground for the upcoming Avengers movie.This film has few flaws, and perhaps our tastes are becoming more sophisticated these days due to using Ironman etc as a yardstick. The main problem is its lack of grounding in reality (or history for that matter.). Fantasy movies should take themselves seriously even if humour is present - again see Ironman, LOTR, original Conan. Otherwise they risk being just silly. With a little more effort in the writing this would've been one of the greats.
My rating 8 or 8.5 out of 10. I'll be buying it in anycase. Hope you enjoy it.
