Would you bring a 1 year old to see Winnie the pooh in the movie theatre?

As you probably know winnie the pooh comes to theaters on Friday. I'm babysitting my neighbors 13 month old daughter Saturday and she wants me to take her out and do something fun. I want to take her to little critters but I'm only 14 and I have no way to get there. My next idea is the Winnie the pooh movie but I dont know if she would be willing to sit in the theatre the entire time and I know im going to have to change at least 1 diaper while were there. Do you think the movies is a bad idea for a 1 year old?
