Also, what's with the shoulders on the guy from the show? It's shaped like scales, but looks like the same material as the breastplate. Sure, armor can have a lot of decoration, but that means he can't lift his arms very high. Boromir has proper, segmented pauldrons. If he lifts his arms up, the plates slide past each other and he's good to go.

Also, armpits are one of the biggest weak points in armor. Boromir gets hit in the armpit (or a point slides off his breastplate into his armpit) and his chainmail has a good chance of stopping it from penetrating or at the very least from getting too deep into him. The Aragorn we have at home is wearing what I will charitably assume is a gambeson, no mail. The tip of a pike or spear slips in and he's got a punctured lung.

You'd think for a billion dollars they could pay a consultant to work with the wardrobe department, especially because they're following up a film series known for absolutely excellent costume design.
