Thanks again @Shepherd
I don't know how true this is, but on the MCU Facebook page there are some individuals who supposedly got to see the first thirty minutes of Infinity War. They couldn't go into specifics for obvious reasons of course, although they did say it was the scene where the Guardians meet Thor. In their brief synopsis, they mention that there were a lot of shifts in tone. The Guardians scenes with Thor brings out a quirky, unique, comedic, and bombastic cosmic feel, later on it switches over to more of the gritty, grounded, and darker aspects of the Captain America movies, with the Avengers in Wakanda and New York. So let's see.
