As an anime fan, I thought it was exactly the introduction I needed before I started with the heavy, threatening brick, its 1500+ pages looming before me. 51 episodes, a quickie.
Well, it was most certainly not. I dropped out at ep 14 because it was so freaking booooooooring. Seriously. So slow-paced and Cosette focused.
While it is probably one of the most faithful adaptions, with a bucketload of squee-worthy animated moments from the book, and I appreciate it for that, I dislike it.
Not only the animation (which sucked) and the addition of a lot of cute extras (the dog, Alain, Cosette's and Gavroche's sibling relationship), but how the message Les Misérables tries to convey is twisted.
For instance, Gavroche's death in the book was a symbol of how war and destruction will not halt, even when faced with the purest of innocence (Hugo wrote a lot about Gavroche and his background. Almost as much as Fantine. And he had put special care into making the character likeable. Wise for his age, witty, sharp-tongued, funny, street, yet a child, innocent like all children). The fact that he survives does partly destroy the message.
Secondly, Les Amis die. And I must say that, while I love the animation of Enjolras' death scene and it made me cry buckets of tears, if their purpose was to create a lollipop-mountain soda-lake cotton-candy tree world like they made it seem by letting Gavroche and Javert live, they could have spared Les Amis
But I do agree that it is a nice introduction for children and all.
