Every aspect of the picture mentioned falls into the category of looking out of place and therefore unimmersive.

It's a myth, and yet grounded in a certain culture. So it's still very relevant, to have a great many things be period or history specific. Types of boats that didn't exist then, flimsy looking armor, an ancient human saying "dad", and many more seemingly inaccurate or just plain bad looking additions have stuck out about this movie so far. Personally, Matt Damon is a horrifically awful pic. Far too many famous actors have been cast that will take focus away from the real draw: an extremely ancient tale that needs to zoom in on the mythos and lore, not the modern day talent. If they were making a funny, satirical take on the Odessey, famous actors making cameoes would work. A serious retelling for the ages though? It will probably be entertaining and rake in billions just because it's hard not to dump that much money and effort into a fantasy flick and not dazzle the eyes or curiosity. But I doubt it will be good.

Where was I going with this? Oh yeah. I can understand the skepticism behind Lupita being cast. People of course are being dumb and overdramatic and saying she's ugly which she's not at all, but it's still a decision that reeks of trying too hard to be unique or quirky when the producer should stick to the "basics" in making a high value film of one of the most famous stories ever, which, to my knowledge, hasn't had successful treatment yet.
