The Muppets are terribly underutilized, so maybe this is a good sign. I haven't even heard anything on the new movie in ages, wonder if it's even still happening?
The Muppets have very little to do with Disneyland, so it's an interesting choice for an advertising campaign.
I think it could be very effective if done well. Advertisements featuring Muppets in Disneyland could be entertaining in their own right. It's the kind of thing I'd seek out and watch on YouTube or Disneyland.com or wherever.
Could be a win-win situation. The Muppets get some much needed exposure and if people like me are willing to seek out the clips, Disneyland some gets free advertising.
