Prélude

No pun intended - I am not sure if it helps to be fluent in the piano (read music) world. But I reckon it probably wouldn't hurt. Comparing this to black swan (this being a mirror to that just not in the world of ... well ballet, but piano) kind of makes sense.

The acting is quite good, the pace is quite slow to say the least. I have seen more engaging movies with similar themes and topics. But this still has the script and the actors going for it. Again, you have to have the patience for it and you have to like dramas with a bit of a darker touch. Anyone who wants to be on top (no pun intended) has to sacrifice things ... sometimes that may be sanity (of the viewer? You decide) ...
