That last song was def awkward (as were other moments) but I thoroughly enjoyed the rest. I think between my love of Broadway, Glee, and Tyler Perry plays, I am no longer phased by people randomly breaking into song. Only the first time did it startle me but most of it was beautiful/entertaining.
Meredith broke my heart.
Teddy pissed me off.
Aaaaaand great, now "Grace" is stuck in my head.
