I already liked Pushing Daisies, but I did think that the dialogue occasionally pushed it in terms of sweetness. Then I realized that the leads talk in what might seem to be an overly affectionate way because it's almost the only form of affection they can show each other, not being able to touch. Knowing that, it's only natural that their dialogue would sound odd compared to the way most couples talk.
Also, considering that both of them led extremely sheltered lives before meeting each other again, it's a bit easier to accept. In fact, Pushing Daisies inspires a lot of these moments, when you look at the TV and say "Oh, come on, that's too sappy to be believed!" but then you realize that you're smiling too much to mind. (Amazingly Enough)
I was watching the credits, when I found myself staring at the daisy and the bee. Then it hit me - it's Ned and Chuck. Notice how the bee never touches the flower? Chuck was a beekeeper, and Ned, well, you know. Nice symbolism, man.
In "Bitter Sweets", Ned tells Chuck "don't go over to the Dark Side". In an earlier episode, his swordfighting skills are explained as his having wanted to be a Jedi when he was a kid, so the mention of the Dark Side is just another example of his being a Star Wars fan. Not earth-shattering, but an excellent bit of continuity.
During that whole thing about Chuck moving out, Ned was quite distraught. Understandable under nearly any circumstances, but it was only recently I realized how really, truly alone he had been his entire life, and how much Chuck served to rectify that. The idea of her leaving him, even just to a room across the hall, brought with it the fear he might be left lonely and miserable again.
When Ned and Randy had their conversation about Superman and Clark Kent, it seemed to me that Randy had given this a lot of thought for someone who didn't know about Ned's powers. Then it hit me that Randy was talking about himself—because he's just the sort of regular guy that Clark Kent (or Ned) would be if he didn't have superpowers. The line "nobody gave a crap about Clark Kent" suddenly speaks volumes about how lonely and ignored he's always felt. And, as the narrator points out, Olive loves Ned even though she only knows the "Clark Kent" side, which makes it all the sweeter that she ends up with Randy in the end.
