As the previous reviewer questioned.."Why did this series not catch on?" "Beethoven" or "Genius of Beethoven" is a very compelling account of Beethoven's life, legend, love, and most of all music. Probably the most accurate portrayal of the master's life, albeit Paul Rhys doesn't look exactly like Beethoven (according to most descriptions), but the acting was very good.
After watching the series, I've come to realize it's challenging to understand any piece completely, unless you understand the context in which it was written. This movie teaches and explains the awesome intricacies of each major piece of Beethoven's works and allows you to experience the music from the most accurate perspective.
Only small criticism I can point out is that there are some musical scenes that are too drawn out. e.g. if you really don't care about Beethoven's opera, the entire section that describes his opera in detail - I fell asleep during.
Beethoven's becoming a "lost gem", but probably just the entire genre of classical music being slowly forgotten by the Britney Spears & Justin Timberlake admiring public.
