Yes it is tension. You’re just clinging onto the way you saw the film as a child and refusing to see it from any other perspective.
No, I just think the prequels are crap for a multitude of reasons, screwing up Anakin’s fall is one of them. No tricks prequel defenders use have really worked on me and I’m a guy who grew up with the prequels! They’re still terribly executed movies, and yes, I believe Clone Wars makes them a much worse experience. That Anakin is much more believable as the person talked about in the OT and as the future Vader.
