This is a really, really good animated family movie. It is a perfect blend of funny characters, decent story and little jokes spread around in the animation.
Almost all characters are very likable and funny, each in a different way. The actual story has quite a bit of suspense (for an animated family film) while still being sufficiently light and funny. Actually it is kind of two stories. One is the story of Judy Hopps fighting to prove herself as a police officer and the other is the more sinister evil plot that she attempts to unravel.
The movie moves at a good enough speed leaving enough room to both tell the story itself and inserting jokes and comical situations. The two bureaucratic sloths were quite fun already in their first scenes but the last scene with them at the very end of the movie was absolutely hilarious.
The animation itself was certainly adequate although I sometimes miss the old hand drawn animations from Walt Disney.
Overall, one of the better, if not the best, animated movie I have watched in quite a while.
