Released in 2021, "Eternals" was initially hailed as a significant breakthrough for Marvel Studios. Directed by Oscar-winning filmmaker Chloé Zhao and boasting a cast even more star-studded than "The Avengers," the film generated immense anticipation among fans.
However, the film ultimately became the first Marvel entry to receive a "Rotten" rating on Rotten Tomatoes. Its box office gross of only $402 million failed to make a significant splash in the post-pandemic market. 
While the film still contained many commendable elements, its overly ambitious character roster and plot design made it difficult for audiences to fully engage. Four years after its release, Marvel has yet to announce any sequel plans, nor has it addressed the post-credits cliffhangers, and the characters have not appeared in any other MCU projects.
Zhao, meanwhile, has moved on to her new film, "Hamnet," which centers on the tragic love story of William Shakespeare and his wife, Anne Hathaway. In an interview with "Vanity Fair," she discussed how directing "Eternals," despite its challenges, provided her with invaluable experience. 
She explained that "Eternals" helped prepare her for "Hamnet" because it involved a different kind of world-building. Zhao noted that prior to "Eternals," she had only directed stories set in the real world, and the experience taught her what was feasible and what was not in large-scale productions.
Zhao further elaborated that "Eternals" had almost unlimited funding and resources, and that this lack of constraints proved dangerous. She contrasted this with "Hamnet," where they could only afford one street corner set, which made every detail meaningful. In contrast, she felt that "Eternals" lost its creative focus due to an abundance of resources. 
She also recalled that the MCU's filmmaking approach differed significantly from her ideal creative process. Zhao described it as a "machine-made" film, where one could only fully commit to the process and hope for an ideal outcome, which ultimately wasn't the case. She emphasized that this experience served as a learning curve for her, helping her better understand how to balance large-scale productions with her personal style.
