I like the idea of the bait and switch, but there wasn't a single funny scene to me there, and they didn't show enough of the Muppets to indicate that they are any different from what we've seen over the last 10-15 years. The Fozzie comment at the end was kind of cool because it seemed to reference something from the beginning of the Great Muppet Caper (which was charming in the context of that movie). But even there, it's kind of a throw-away line and not the kind of thing you want to include in a trailer IMO.
