First off, it was terrible, heartbreaking, awful, saddening, amazing, and possibly the best Marvel movie to date.

Actually, scratch that - the best Marvel movie to date, no question, it's a done deal. It didn't only live up to the hype; it exceeded it.
Thor's powers. Can we talk about Stormbreaker, and him kicking the Outriders asses? Like, wow! He won that fight. He won that fight for everyone.

Loki and Heimdall's deaths were in the first five minutes of the film. Unexpected for me. I'd heard rumors about Loki's death, and since he's died a few times in the past, I didn't expect his death to be so absolute. It was very, very sad, though I feel it was necessary.

I felt bad for Thanos. There, I said it. He really did love Gamora, despite his insanity and his evil agenda. He genuinely believed that what he was doing was right. Thanos had a motive. He was a sympathetic character. He became my favorite villain, instantly. Thanos killed everyone, mercilessly and relentlessly. But I somehow felt sorry for him. Not many characters can do that, but the Russos executed that aspect perfectly and seamlessly. Incredible and terrifying.
10/10. Definitely the best Marvel film to date. I thoroughly enjoyed it, and it made me happy,sad,itt made me laugh, and want to scream. Not many movies can do that, and spark that much emotion into the audience. It took you through every emotion in the book.
