And despite what some people think, I love the Sound of Music rip-off part. Sometimes I think this scene should have come before the first kiss scene though. You're not the only one; I believe the IMAX version switched them around. But I prefer them as they are. Their first kiss is awkward, uncomfortable, and mostly an aggressive move on Anakin's part. The whole point of the picnic scene is that they become physically and emotionally comfortable with each other, as well as portray Padme as a willing and engaged participant in the relationship. The tense air would have seemed even more awkward and bizarre if it was prefaced with a scene where Padme was rolling with Anakin in a field - a far more phyiscally intimate act, I'd say, then letting him touch her back or kiss her.
