I have never seen the series, so cant judge if this is a good or bad adaptation all I can say this is a truly funny film though aimed at children is funny enough to keep me entertained.
The animation is uniformly excellent and honestly kept me guessing from the start to the end whether it was CGI or stop motion, I am still not sure even after reading all the credits. Maybe I didn't read them properly because the theme tune is very catchy and bounces round the head even now.
The story is easy to follow, the characters are likable and there is no trite wince inducing dialogue, everything is mumbled by the humans and the sheep communicate in a variations of bahs. There are some cracking running gags and a smattering of fart jokes. The sheep in disguise have to be seen to believed and the viewer would be surprised what goes on with a horse.
The closing credits though long are a fun roll with a funny bit at the end.
Watch it. I bet The Interview wont be as much fun.
