This is not a documentary and as such don't expect too much depth or insight from this portrayal of Liszt, or else most of audience might be bored to death. Who cares about his study with Czerny or his religious faith in such a film anyway?
Instead, we have quite a lot of romances with pretty faces, elegant dresses and magnificent palaces. There was even a brief mention about Chopin and Wagner in the background. Visual effect was excellent and even the actor on the piano was so remarkable.
I'm not too sure though if Boglet would suit the taste of all piano lovers, probably not: Liszt is Liszt, who can compare with him when even Anton Rubinstein wanted to be his pupil. But for the general audience, it's just marvelous. The sound is wonderful too, not just the music,the dialoges too.
The plot was forceful and the rhythm fast and there is not a single scene that is boring. The result: one could easily sit still in front of it for the whole length of 130 minutes and for twice.
Highly recommended.
