I went in kinda expecting to not like the movie since a lot of people were complaining about it but I kinda enjoyed it?
I think it is kinda slow because of the whole backstory and finding all the other Eternals when Ajak died, or the whole history of how they protect Earth, and there is less action compared to other Marvel movies but I didn't mind it since it is the first time we are being introduced to them.
Also, can I just say the action scenes were so good? I love how everyone's powers are unique and played out differently in combat. Seriously the fighting scenes were amazing, Bucky Ikaris felt more superman than superman himself. Makkari's superspeed with her sonic booms were so fun to watch seeing the actual impact of speed rather than the whole "slow-mo" sequence they usually do for speedsters. Thena's fighting was so amazing Angelina Jolie absolutely nailed it and Phastos technology fighting style I love it. Sersi was amazing too her powers are so unique.
I really hope they bring back the dead Eternals because it's such a shame to lose 3 of them. Even though Ikaris is the "villian" he isn't exactly one it's just his moral compass being confused and I kinda feel for him, and eventually he chose love instead. Also, not Don Lee sacrificing himself to save his wife in Train to Busan, and also sacrificing himself to save Thena in this movie my heart
