This is better done than I imagined it would be. By far honestly.

Ok. I just watched this.

A couple things.

1. I don't consider this scene from a New Hope to be bad. Perhaps that's nostalgia blinders? I've heard people say it's hokey and even George Lucas seems to dog it when he talks about it. That said I've always considered it to be fine, if not a bit bland which this fixes but with a few downsides and not a lot of upside.

2. I always viewed the old New Hope fight as Obi Wan not really trying to kill Vader and it seemed like Vader was holding back too. Like Vader and Obi Wan were just talking and not really trying to kill each other. At the point in the story, Obi Wan wanted to stall Vader and let Leia, Luke and Han escape. The fight was on his terms and at no point did Vader ever "get Obi Wan" or hurt him because he couldn't. I'd argue because Obi Wan was so powerful, Vader couldn't have but winning in that way wasn't Obi Wan's goal. Frankly I think this makes Luke's last stand in the Last Jedi even more powerful it's a direct mirror of this fight in a New Hope. Luke exiting the scene just like his teacher. And this video doesn't seem to revel in that, it's just Vader being a badass and Obi Wan getting knocked around and seems to imply he's Vaders lesser, which I think isn't how I look at it.

3. When Obi Wan loses in this version it has less weight because he's simply a less talented Jedi, not because he chooses to save anyone. I think this is a repeat of 2 but it's important.

Fun fight though, thanks for sharing.

One more thing.

I also think something else is going on in this scene. As Obi Wan is trying to stall Vader two things are happening. Firstly Vader is thinking he's toying with Obi Wan and chides him as being weak. Obi Wan stays on message and calls Vader evil, and that he failed as a teacher. I think what Obi Wan is doing is playing weak or not trying to get Vader to focus on toying with him to get him to lose interest in Leia, Luke and Han who are escaping (I didn't forget Chewie, R2 or C3PO). When he realizes they are going to be ok Obi Wan lets go. I don't read this scene as Vader is more powerful, but Obi Wan has a different goal and he's not trying to "out lightsaber Vader" and Vader actually thinks Obi Wan is weak, which I think is a trick Obi Wan is playing on Vader.

After Revenge of the Sith, Vader would have an axe to grind in this way too BUT I imagine that wasn't as well formed when this scene was written and I still think if it wasn't my read makes sense.

Oh and I misspelled Obi-Wan a lot so apologies to everyone reading that dying a little inside. My son has been acting up a bit today and I had to type fast to get this out.

That's always been my read on the scene, and I think Revenge of the Sith strengthens that interpretation. But the fight has always been janky, even if their intentions were stalling/toying with each other. The first time I saw it I interpreted the fight the same as you but chuckled at the choreography a bit. As I have said before I don't have any childhood nostalgia for Star Wars so that may be a factor. The first time I saw it was the special edition in the theater and I actually fell asleep for about 30 minutes in the middle. I've come a long way :D

But I don't think anyone involved said they were trying to fix the scene at any rate, just reimagining it.
