That final flashback scene is emotionally brutal (Spoilers)
Just watched the movie recently, and damn. That final Rocket Raccoon flashback is probably the most emotionally brutal moment I've seen in a movie. And I say that as someone who doesn't even get emotional watching movies, lol. But I actually started tearing up.
The otter being murdered in cold blood, Rocket screaming, High Evolutionary mocking him, Rocket running for his life in the hallway and escaping in the ship, etc. That whole scene was just...I was speechless. They tried to lighten it with humor back in the present, but my theater audience wasn't even laughing.
I enjoyed GOTG3, but it's pretty much a "one and done" movie for me because of that scene. And yes, I know it's just fictional characters, but something about that scene fucked me up.
