it was my favorite MCU movie , it was completely something different and new the story was amazing and i completely disagree with those people that are saying it was a bad movie
(SPOILER) but i didn't like 3 things about the story of this film , first: Ikaris betrayal to others was really shocking and makes me feel bad and i think it could have been better , second: i was very upset that eternals kill a celestial , and not just some celestial it was the most powerful celestial ( in comics at least ) and a celestial is not just a big robot so eternals could kill it easily , third: i don't know about the other people but i think Ikaris suicide wasn't really a good idea
but yeah everything aside from the things above , movie was great but could have been a perfect series
