I have seen this movie many times and even own it. It is excellently written and produced. I have shown it to my piano students to give them a better understanding of the life of Beethoven. It is very definitely kid friendly as opposed to "Immortal Beloved" because of the content.
The young boy goes through an adjustment period after having lost his father, that is compounded by having what appears at first glance to be a monster living upstairs in his house. The 'monster' of course turns out to Beethoven! When showing it to young children as part of a class, it is recommended that one should give a bit of background on exactly who Beethoven is and that these events are not happening in real time. They may tend to buy into the events a little too much. Explanation might also be needed about his deafness. The actor who portrayed Beethoven did a very excellent job of getting across the difficulty of being able to hear so much wonderful music in your head but always knowing the frustration of never being able to actually hear it.
The costumes are very accurate for the period and the cinematography is also very good. I give this movie, eight stars!
