Fair point. I'd argue that Vader's eyebrows is just because you've seen the films with eyebrows. As for the planets, two of them are Tatooine and Cloud City, so those might have looked familiar? The others are Corouscant, which was a strange thing because it had only appeared in books before its 1997 inclusion, and Naboo which was added in 2004 and is PT. So, half the planets are OT, one is bizarrely EU at original time of inclusion (but was obviously Lucas looking towards the Prequels), and Naboo...well, that is PT.

My point: The eyebrows and half the planets are only strange because you've seen the OT before they were changed. Thus, they don't ruin the films, it's only the difference that's jarring. You're right about Corouscant and Naboo, though, if you haven't seen PT.
