There was a not-awful French version of Les Miserables that I had back in the VHS days. The dubbed English not quite ruined it.
Among many other failings, the dramatized versions I have seen completely skipped over the character of Bishop Charles-François-Bienvenu Myriel--a monumental failing. Hugo devoted the entire first fifteen chapters to him and his character. He is one of the greatest characters in all literature and certainly one of my favorites.
I think even to begin to tell this magnificent tale adequately would require something like 20 or 25 episodes, maybe more.
