Coming from Disney, it's shoking that the design, color, ilumination and design is so terrible, with 3D films like Toy Story having aged better with an almost 10 year gap.
The plot is kind of like it doesn't know what it wants to do, where it wants to go, so at the end of the movie it's not clear what the point or conclusion was, wrapped up with terrible characters everywhere, leaving only Chicken Little and his father as two merely "ok" characters.
