This is what it would be like.
It wasn't entirely unwatchable, but it was not a good movie by any means. CGI was distracting, although if you look at it as art, they did a good job, just not realistic enough to be passable.
I was surprised Bernard Rose was the writer and Director, who also did the same for Immortal Beloved. Perhaps this movie was just missing Gary Oldman? The movie seems to be confused whether Paganini is the main character or not. It is filled with sub-par, some acceptable, and some over-acted performances. I thought Andrea Deck was good. David Garrett as Paganini, well, maybe his performance was more related to the script. I did enjoy all his performance scenes (performing on the violin, you dirty minded people you).
Am I the only one that noticed St. Patrick's Cross flag flying over London? You'd think Bernard Rose, an Englishman, would catch that. It was clearly in the hands of the Syfy special effects gurus at this point, so maybe the he had no hand in post-production. Or maybe there was a time England was flying the British version of the Irish flag that I don't know about? I doubt it.
Overall, this movie was not great enough to be good, and not bad enough to be great. It falls right in the middle, as most forgettable movies do.
