Utter garbage

Rating: 1/10 (27 April 2019)

The movie itself establishes time travel as follows: You cannot alter your past to change your future as your past becomes your future. Also, when you alter the past you're creating a rift in the timline creating an completely alternate reality. This is explained by Hulk and The Ancient one, the latter also explains that the new reality wouldnt survive if a Infinity Stone was taken from it.
Despite this Cap is able to leave the primary reality that we follow all along, not warp his way but instead stay back in the past, change it, and grow old and ultimately show up on a bench. The scene depics that he is the same Cap but regarding the rules established this is not possible. That is not the same Cap. As soon as he warped to the past and decided to stay with Peggy he changed it and created another reality in which he grows old.
And if a reality cannot survive without ONE stone how is the primary reality able to when Cap takes them all away to their original timeline?
Sloppy.
