It seems that Nolan might have missed the point of the Odyssey altogether as most people do. It's not the story of a hero beset by the ill will of the gods; it's the story of a charming rogue or conman. Odysseus is described in the very first verse of Homer's poem as "πολύτροπον" (polytropon; "he of many turns") which has been variously translated as "a complicated man", "a much-travelled man" or "a resourceful man", but a more appropriate meaning might be "a devious man", "a shifty man" or "a crafty man".
Odysseus tells his increasingly incredible tales to elicit support and make his way home - possible after having taken part in various Sea Peoples' raids in the Eastern Mediterranean. Once one realises Odysseus's true nature, it changes how one interprets the story. One is either taken in completely by his fabrications or one enjoys his ridiculous shaggy dog stories. In many respects, it reminds me of the far-fetched exploits related by Rudolf Erich Raspe in Baron Munchausen's Narrative of His Marvellous Travels and Campaigns in Russia.
The Coen brothers got much nearer the mark with George Clooney's portrayal of Ulysses Everett McGill in O Borther, Where Art Thou?
Let's not go into the armour not being appropriate for the late Bronze Age - even Homer, who was reputedly blind, had accurate knowledge of the style of armour worn by the Achaeans, the Danaans and the Argives - as is related in the Iliad and the Odyssey. I seem to recall that the movie Troy got that detail more correct, but not some others. It's not something that a modern audience is going to care about.
However, I will withhold judgement until I have seen the movie.
