This would be a good show even without the mimicking set-pieces (which could get old...) It's slow-paced but the writer seems to know where it's going and the core cast are all sympathetically drawn, and a lot of mileage is made from them trying to *avoid* conflict.
I like the flair for well-timed visual details like the floating Titanic at the end of Ep2 and the drawn-on underpants near the beginning of the last one. It's details like this that go above and beyond the show's underlying sweetness and rather-corny set pieces.
And yeah "who needs you, you stupid cow?" was hilarious.
