Lets all love Lain
My point isn't what the ultimate result was. It's the misconception that Obi-Wan was "controlling" or "leading" the fight, as if it were a dance. The film shows him simply reacting to Anakin's onslaught, which he did. But not with some foresight or greater plan driving him. The novel states that outside was where they should go, as the Force told him or whatever.
That's about it. It's all from Kenobi's perspective and he has two epiphanies throughout--one about how much he love Anakin and the other about letting go. But during the actual combat, Anakin was very clearly the dominant force. He was manipulating, aiming, and pulling the triggers of the rifles of the soldiers he'd killed. Obi-Wan just barely caught the bolts and sent them back at Anakin (an act of "desperation"😉, and Anakin easily, "contemptuously" deflected them. He was sent hurling in to the far wall with a Force push (and only survived because of his "one last trick"😉 and then proceeded to be manhandled by Anakin, who almost broke his arms off.
Combat-wise that's where all the specific stuff stops. It become a general narrative of the outdoor scene, with neither holding any advantage. The last part has Obi-Wan spear-diving at Anakin, who easily dodges it and curses that he let Obi-Wan trick him in to reaching the shoreline.
The duel is comparatively one-sided. Obi-Wan would have died very early on if Anakin was his lucid "z0ne" self. He wasn't "directing" the fight, he was simply reacting to opportune moments (he seems to excel at that). But straight out combat? Nuh uh. RotS Vader>>Obi-Wan.
That's the novel's narrative anyway. It doesn't include the Force-stalemate and has far more pro-Anakin fight scenes. The movie displays a more even duel. So what do we pick? The extrapolated narrative, or the more-open-to-interpretation-but-higher-canon-movie?
