The bar is set high

Rating: 8/10 (7 July 2015)

And therefor it's not as surprising to see/hear people being disappointed in the outcome. But the movie itself is more than decent, if you watch it free of any comparisons. And I don't mean free as in not connected (Guardians of the Galaxy can be seen as that), but as in not comparing it in scale or humor to the other entries in the franchise. Phase 3 is a go after this.
Since I'm not that familiar with the comics themselves I cannot compare nor am I "biased" or preoccupied/preconceived by anything. So characters coming up and the interpretation of them are fresh as they are presented. It might take the "easy" way out in some cases, but overall the odds are against stacked against our heroes.
Apart from building up on the previous build ups and Hawkeye/Widow getting more screen time, what I do like, is the fact that you get little jokes throughout the movie. The "language" joke might annoy some, but I like little gems like that myself. Obviously some people are fed up with Superhero movies, but that won't change the fact, that they are here to stay ... and entertain if you let them
