When i went to see MFS the second time, I remember clear as a bell there were kids freaking out over how loud the movie was and how big the movie was and they just screamed until the movie actually started.I saw it a third time, this time at the Movie Tavern, which gets a more adult audience. There was a lot of laughter this time around, which pleased me. There was one little girl, I'd guess about 5 years old, who kept getting freaked out and wanting to leave whenever Tex Richman started doing his thing. She was OK again when the movie went back to Muppetness. This stuck out in my mind because the last showing I went to, there was a little kid who kept getting very vocally upset at the same things.
Thankfully the kids that wend to this movie when I saw it (things came up and I couldn't see it again yet) were older and quieter.
