The only problem I have is the music. I didn't really get into it, except for "Catchy Song" and the Everything Is Awesome remix. I felt the music took up about 1/4 of the movie, which I didn't like. Other than that, this movie was AWESOME. The story was engaging, the plot twist was unexpected, the animation was excellent, and the characters were likable. Go see this movie on the big screen now!
