It has all the ingredients that will make a typical film work but it misses its heartbeat. The heart is in the right place but I wish the heartbeat too was rhythmic. It rises then stays flat and to rise again so that's the wave of the heartbeat of the film. It's likable but definitely not lovable.
The quality of animation is good as it is least expected in any animation film these days coming out of Hollywood. I dare say Animation Industry has become a parallel industry to the mainstream Hollywood and in Animation there are gem-like films. PIXAR is one of the finest places in Animation films while other studios have their hits and misses. Warner Animation Group, the producer of this film earlier made "The Lego Movie" which was fun but this film lacked fun. Yes, there are funny moments but they are not as many as anticipated in an animation film.
I am not wasting more words or time in reviewing this,. But for me, it was an average outing and I am going with 2/5.
