I never thought I feel very sad and emotional for any raccoon my whole LIFE. But yeah, its a pretty good back story about the "Rocket The Raccoon."
In this third part of the movie, he gives equal space and dialogue to all the characters. Even the humor did very well with the timing of the movie and dialogues. I heard happy, cracking laughs throughout the film.
Do I watch it again? Sure, I will. It is that good.
Give it a try on Imax or in a good 3d theater.
