I watched age of ultron after infinity war and the dialogues on it has so much meaning, feels like a deeper movie than at the time, ultron says some things that you find the meaning after thanos appears and starts doing his thing, or its just me?

Age of Ultron just seems stupid now!

Yes on some points it feels deeper when Ultron say that things but even IW is more deeper than AOU.

All the dreams which Scarlett whitch showed were related to infinity war

Yes it feel different

Yes as the destruction that Ultron saw could be referring to Thanos
