>>212033178Dude, the MCU movies back then were all about magical stones, and how related they were to each other, and what they were for.
Captain America had the tessaract, The Avengers had Loki using another one to control minds, and then came Guardians and the marketing sold that as being the movie to watch for to get all the answers, with the villain get his gem/stone from Thanos himself, who people would finally see in all his glory after that small tease in the Avengers.
That was the marketing at the time. Go see this shit to finally see Thanos and get some of the answers, because it is going to matter for the next Avengers movie.
Stop lying to yourself that this wasn't the case.
