Yes, seeing that he was involved really filled me with peace with the whole thing. LIke I said, I'm a nanny, so Mary Poppins is VERY important to me, and while I was sort of jazzed about their being a new one (sometimes it's hard to introduce littles to old-timey stuff) ;), I was terrified that they were going to bastardize it and that the new Mary and Bert were going to ruin it. But then when I saw that he was the new Bert (for all intent and purposes) it just relaxed me. And yes, he wouldn't be responsible if it were still garbage, but it did give me a sense that it had to be a quality for him to get involved, plus I felt he'd have a bit of influence in making it better.
