I thought having Makkari be deaf made a lot of sense given her speed ability. The sonic booms would be deafening after all, so being dear made it easier for her to run without worrying about the sound. She was criminally underused though. Same with Druig and Gilgamesh.
If a second Eternals film happens, let's hope they really hone in on the remaining characters (and the one/two new ones as seen in the mid-credits scene) and give them solid plots/motivations.
There's been a lot of chatter about how this might have been better served as a Disney+ series with an episode focusing on an Eternal or two. I could've seen them stretch and flesh things out with an episode about Sersi and Sprite living in London, another full one about Thena and Gilgamesh, one for Druig and Kingo and their opposing lifestyles (the former becoming reclusive while the latter basks in the spotlight), one for Phastos (because he reeeeeally needed more), and one for Ajak and Ikaris. Then pepper Makkari throughout each of them as she speeds across the world through different ages of mankind gathering items for her collection.
Honestly, I would like it more if we saw then all again in a Disney+ series rather than a film, but we know they want a huge budget for it so it'll probably be another 2.5 hour film rather than a 6-episode series. Maybe we can get a prequel series starring the ones who weren't fleshed out in the film like Phastos, Makkari, and Gilgamesh?
As for my personal ranking, it lands 18th out of the 26 films released so far, but depending on how the film is recontextualized with future installments, it could move up later on.
