The titles say less and less about whom the Marvel films are about. In “Infinity War” the Avengers are no longer complete (Hawkeye died somewhere) and also here we have Spider Man, the Guardians of the Galaxy, Dr. Strange, Thor, there is even a part set in Wakanda, the bad guy is Thanos again. You get it, the Marvel movies are beginning to be like someone asking the entire cast who feels like playing in another movie and all characters of the actors who say ‘yes’ are written in. Think of a name, an there is another addition to the franchise.
“Infinity War” is another extraterrestrial spectacle. Thanos is after all the infinity stones and he is well on his way. Should he be able to get them all in his specially crafted glove, he would have infinite power and hence: destroy the universe. He is the bad guy after all, is he not?
Thor had some of the stones, but Thanos gets it in the opening scenes of the film. Also Dr. Strange appears to get his powers from one of the stones, so he is sought after as well. Vision, who grew out of the AI of Tony Stark (Iron Man) has one in his head as well. Different troupes who either or not met before get together. The Avengers meet the Guardians of the Galaxy, Iron Man meets Dr. Strange, etc. There are amusing references to earlier films such as Captain America asking about Thor’s new haircut (shorter) and Thor about his new beard or the Black Panther who shouts that Captain America needs a new shield.
Story wise there are not a whole lot of surprises. Thanos has the upper hand all the way to the end, but I will not give a big spoiler when I tell you he does not make it.
