I remember watching the old Fraggle Rocks as a kid and (glorious as the episodes are) noting the green-screen edges especially around Fraggle hair. Many people have raised concerns about CG effects and modernizing the "look" of the Fraggles. I think it's great that this film is coming around at a time when effects have become more sophisticated. Green-screen techniques will shine in this film as will others. It would be great to see the odd CG Doozer scampering about the ground in some wide shots, but I do hope and believe that practical effects, perfected while the program was still on the air, will be the primary focus. CG can be used to enhance the Fraggle world. It shouldn't take over it. The Fraggle puppets themselves are fairly simple looking. They are masterfully constructed and performed. That's the part that brings the life to Fraggle Rock. Henson’s Fraggles and Muppets have always been about craftsmanship. Sometimes this craftsmanship is infused with a bit of technology.
