I remember going to it twice. My oldest had just turned 8 and I wasn't sure quite yet what the tone and content of these films were going to be and whether they would be appropriate for a kid of his age. Both times I watched it, I was just giddy with what they were building and where it was going. There's been very few scenes from these films that have really created a lasting impact on me. That scene from Avengers, Stormbreaker's creation and Thor's subsequent arrival back on Earth in Infinity War, Cap first picking up Mjolnir, and the Avengers Assemble scene from End Game.
There still something about the costumes in that film that make it feel dated, but not enough to completely distract from the story. It seems like a lifetime ago, and in some way it really was.
