Honestly people are focused way too much on the historical accuracy of the movie. I’m an archaeologist and managed to just enjoy it as a modern retelling of an old story.

The Bronze age collapse they brought up had nothing to do with the transition to Iron. It had everything to do with the collapse of their society. Which is something they touch on constantly with the suitors and their disregard of social rules.

As for whether or not they considered it a “bronze age” maybe not so directly but bronze was very important. Someone that was educated and could read, like a king, would know that they would not be able to produce bronze after a collapse in trade. Bronze production relied heavily on the trade routes to access tin. I actually quite enjoyed this idea that the Greeks who sacked Troy as the Sea Peoples. No it doesn’t line up well with the history but it was a fun take nevertheless.

And sure, there were constant historical inaccuracies. The armor (Agamemnon in particular), the ships, the weapons, all wrong, but honestly it doesn’t matter. Sirens and cyclops aren’t historically accurate either. Sometimes you just gotta enjoy the story.
