Alright, look
The helmets from the era of the rebellion in the Roman Empire were basically those Gallic-style ones, you know, with the neck guard; they were made of steel using rivets, which just made the whole process way more complicated.
Armor back then was "lorica segmentata," which looked like 10cm wide metal plates laced together into a vest.
Handheld shields were squared off with rounded edges because of how the cohorts actually fought.
But in the movie, we see a helmet from a much later period with "better" protection covering the whole neck and the sides of the face, though those were usually cast bronze to save money and because they could be molded in pieces.
The armor shown is "lorica hamata," which is basically chainmail—either a vest or a full jacket made of interlocking metal rings.
And here, the shields are rounded.
That style was introduced after another military "reform" in the Roman army when they started hiring more "barbarian" reservists to guard the borders; about 60% of them ended up serving in the cavalry, and cavalrymen don't need these massive rectangular shields—they need something lighter and rounded so it doesn't get in the way while they're maneuvering on horseback.
That reform happened during the era of the Pax Romana.
I still don't think it's a "huge" deal for a single movie, but it's definitely one of those things that jumped out at me immediately.😉
