I liked this episode. It was the first one after Light's loss of his Death Note that didn't bore me. And it was great to see Misa in action. I've got to give props to her, but I think the way she went about it was bad. She gave herself away, and I even think L noticed her change. But I'm glad to see her memories return, now Light needs to hurry up and be revived!
It seems like the series is finally coming out of stagnation, but I won't be happy until Ryuk comes back. Although Rem has a certain twang about her, I still like the quirkiness of Ryuk.
