My (8yo) daughter doesn't seem to be particularly interested in seeing the Muppets, and I suppose I haven't done a great job selling it. It makes me sad, but I'm not going to force her to go. We agree on 'Phineas and Ferb', although having that guest spot by Slash in the movie was a bad move on their part.
I watched the 'Rock-afire' doc, which brought on much ribbing and jibes from both my daughter and my wife. I liked it quite a lot. The part that got to me the most was not the 80s nostalgia, but the bit where Fechter visits the empty offices of Creative Engineering and talks about how at one time there were 300 people working there doing all manner of creative and fun things, and then he gradually had to let everybody go.
Frankly, during the 80s I thought the show was pretty goofy.
