Okay so now you actually are saying that. Jesus
Both are absolutely pointless to the OT, much like TESB is pointless to SW.
The difference between the PT and the ST is that there was a story to tell in the PT, and there’s no story left to be told after RotJ. If they don’t really expand every aspect of the universe and make it interesting that is, like TESB, which they did to an extent, even if rehashing the OT to a large degree.
So the ST is more pointless than the PT but of course better.
