Will try to enjoy ep 9 for whatever it is, but yeah, I can see the ST being mostly just forgotten as time goes on, even if the hate for it eventually diminishes. If they keep doing better with other Star Wars projects, be it spinoff films or other shows, etc, the ST will especially be buried in the hearts and memories of people... Not dissimilar to how the Clone Wars shows, games, and such are more remembered by me than the prequel films themself I guess.
And yeah, to be fair to Hayden, it would be hard to take anyone/any actor seriously with grade A dialogue like "From my point of view the Jedi are evil!".
