Ultimately we think it’s a good thing that Guardians of the Galaxy Vol. 2 has opted to avoid the use of Infinity Stones.
All that being said, we cannot ignore the fact that the Infinity Stones are about to play a major role in the Marvel Cinematic Universe.
From the earliest days of the Marvel Cinematic Universe, the studio pretty much built this particular franchise of movies around a central set of McGuffins: the Infinity Stones.
The first Guardians of the Galaxy completely centered upon the titular ensemble of misfit heroes seeking out and protecting one of the five Infinity Stones.
