We've taken the kids to the Campfire movie. They enjoyed it and yes we would do it again if we were staying at the campground or WL but I would not plan my day around it. If I remember correctly Chip n' Dale come out and do some dancing around and there is a sing-a-long and joke telling (of course I may be getting the joke telling confused with when we did it as kids 30+ years ago and not when my kids did it 2 years ago). You can also make s'more. You can bring your own makings or they sell stuff there to make them including the sticks. I was concerned about the s'more making as it is around 2 fire rings and I would assume if it was crowded there may be some unintentional pushing. Luckily when we went we had 1 ring almost completely to ourselves so we were able to stand near our DD's.
The petting zoo is nice. The animals were inside cages so it is not like the animals were walkiing around right next to you. I thought I read somewhere on the this board the the petting area had been changed around.
I would do this more as a down relaxing day away from the parks then as part of a park day unless you take the boat over fom MK to do the petting zoo as a change of scenery for the kids.
