*spoilers* Time-travel
The time-travel twists and turns made even less sense than Back to the Future, despite the jibes at the latter.
It seems none of the characters' interactions in the past had any real impact. Everything still ended up as before, despite Loki absconding with the Tesseract and Thanos' defeat before the events of Guardians of the Galaxy/The Battle of Xandar.*
*On that point, does that mean Ronan and Korath are still alive and will come back for a future film (likely with Captain Marvel making a reappearance)?
Oh, I'm confused.
