I liked it, and although I've always liked Peter, I kind of hope that he doesn't come back.
I see many people wanting "things to go back to the way they were", these kinds of thoughts are what holds life and human evolution back. Stick with this change and when even more changes come further down the line maybe they lead to something "amazing" again, but that's new.
Stick with the old and progression crawls along and our lives are dull and repetitive.
Embrace change, keep positive and we all get somewhere better quicker.
