Gravity is a thing. It’s harder to walk uphill than downhill. It’s harder to swing a sword up than it is down. It really is as simple as that.
Plus, think in terms of literature, and what this means from a story perspective. When Obi-Wan says, “I have the high ground,” he’s not just pointing this out as a fact. He’s offering Anakin a way to safely surrender and save himself. Obi-Wan doesn’t want anyone to get hurt.
But Anakin jumps anyway, and the audience knows he’s crossed the final line. ***His character arc*** is the thing that really hits the ground with a thud.
