I find that a lot of people watch this movie purely for Till. In fact this is the exact reason I found myself clicking the video link. My excitement for a cute movie with funny scenes were high; since people had suggested this would be the case. But I have to say that I was disappointed with it from start to finish.
At times the plot felt dead and the acting following it. The bad guys were like slapstick characters gone horribly wrong. I couldn't get attached to any of it and often found myself just wanting to skip parts. I just feel like there was so much potential that went wasted in the long run.
Young children may enjoy the connection with the main kid and maybe the fact of penguins (if they understand German). Other than that it isn't one I will be running around showing people.
If you want to see it for Till, I recommend just watching the youtube video of his scenes.
