Wishlist (First in a Series)
I wish that R2's "hero" scene in Attack of the Clones was better. Really, the only thing he did in the whole movie was save Padme from molten steel in the droid foundry, and that felt really tacked-on. It was like, "whoops, we forgot the R2-saves-the-day moment, better come up with one quick." Plus the fact that it was our introduction to his (controversial) rocket boosters made it all the more suspect.
I have an idea for how to make it better, but I think that post will need to wait for another day.
