Not good enough as my expectation...
The robot trying too hard to be robotic even we know its a robot.
Too much conversation or self monologue.
No heart-touching drama.
And finally, even the island animals got to survive winter, the wild life(the nature law-eating each other to survive) wouldn't be changed at all, so there is no point they had survived the winter with the help of the robot.
Only the savers of this animation are that main character is a robot, and nature scenes.
Overall, not good enough which is made by Dreamworks?
