It is a tiring movie. That is not a good sign. It took me two days to see it and not even the good stuff (with 45 minutes to go) saves the film from catastrophe. Let's start with the obvious: history doesn't hook. The decadence of some heroes (bad Thor and worse Hulk who looks like the green version of Beast from the XMEN), the tendency to be sentimental killing some characters, showing a powerful villain but with little intuition to handle situations where he has all the to win, to show a key character for his power who appears only at the end to show that even a superhero does not care about the shedding of innocent blood ... The directors were not more talented in handling a story that would have been more digestible if instead of an agonizingly long movie it had been made in two parts. There are two moments where the movie is saved: one is when Robert Downey Jr. Meets his father, the other is when Tom Holland shows a Spiderboy with sensitivity and stupidity. Nothing to rescue from the rest except the wink to the fans of Community (also of the Russo brothers) since they placed one of the leading actresses of that show. It is a movie that falls into the category of "impossible to watch twice". If Thanos were real, the first thing he should do is evaporate those in charge of Marvel and Disney for giving us this ordeal in the form of a pretentious and worthless film.
