The loose ends were there to sequel/franchise bait (Loki's, series though, is something I'm pretty much anticipating), but by God was the movie so satisfying, and yes, I did feel my love for it beat loud again each minute I sat in my seat and watched. Tony's end, while sad and still damn...
It took a while to settle down after that, but you could really see that everyone watching was into it. It's like even the fictional Avengers became IRL heroes, even if just then. It really amped up the atmo!
That movie, man. So many emotions in 3 hours. I can still remember how hard the entire cinema cheered when everyone came in via portals for the final battle
Aaaaand there goes my glass of milk
Also in the original Red and Blue versions, Mew did give birth to Mewtwo, scientists just modified the baby so uuuuuh
