Yeah haha must admit I’m struggling with the over analysis here. I guess people are just excited to talk about multiple universes or something, which is fair enough.

The story seems like quite a straight forward love vs expectation one. Be thankful for what you have, not what you could or should have.

The science works enough to facilitate the plot if you don’t poke it too hard and that’s all you can ask for. Beyond that it’s just an incredibly stylistic, heartfelt movie.
