I am please to say that we did make it to Winnie the Pooh. Pk was over the moon. Instead of going to one of the big Cineplex theatres, we ended up going to a small, art-deco theatre in a nearby town. I will definitely do that again. The matinee tickets were only $5, the sound in the theatre was just right (unlike the last few theatre movies I have seen, when I thought I might have to leave, it was so loud) and the popcorn was yummy. The movie itself wasn't anything terribly exciting but I did laugh out loud a few times and Pk thought it was marvelous. I love the story of Winnie the Pooh and its complexities (I plan to use it as my first read aloud this fall with my grade 2/3 class, it's much less simple than one would think) and yet, there was enough that Pk could understand that she enjoyed it, too.
It was a wonderful outing that we will definitely have to repeat again when another good film comes out - let me know if you know of anything that we might like!
