Marvel's Eternals: Why It Was a Good Idea... But The Execution Was Not.
Eternals is an interesting concept and unique visuals, but slow pacing and rushed character development suggests it should have been a mini-series.

Burleigh grew up in New York City and Los Angeles before attending Dartmouth College and Trinity College Dublin.

The second film takes us on Peter's journey to be understood.
Having Sersi be the central force in Eternals is unprecedented in its viewpoint and focus, from demonstrating a gentle type of leadership, to being overlooked in a group setting but succeeding in the goal at hand anyways, to having romantic options, to strength and integrity, and majority screen time - for a group that's given less screentime than aliens.
Do not trust Rotten Tomatoes. That is what I learned after watching Eternals. Critics currently rate it a 48%, but it's an amazing character-focused Marvel movie with positive diverse representation.
