Well, when I saw the play on Broadway years ago I hated it. And, I didn't hate this movie and had some fun watching it. So, I have to give credit when a film can take source material I hate and make it something watchable.
The cinematography is beautiful and probably my favorite part of the whole thing. And I like Gladiator playing Javert as a dude with mental health issues instead of as the stock villain he was on Broadway. (Though I think Tobin Bell would have been better for the role.)
I hate Borat dude and think he sucked in this as much as he sucks in anything else. But, Bellatrix was awesome and saved several of the Borat Scenes.
Catwoman is only in the film for like 20 minutes, but does a decent job of things. Wolverine does a passable job in his role, which is saying something, because his role is just to be constantly shit on and walk away smiling.
Girl From Every Les Mis Poster was the highlight of the film. Too bad that she's in it for even less time than Catwoman.
Overall fairly good. Not as good as Django, but more cinematic than Argo and certainly better than Zero Dark Thirty.
I will say that the closeups are hella distracting - because the people sing these songs like they are on a stage 20 or 30 feet away from the closest viewer, which skews things emotionally in closeup.
Bottom Line: If you loved the play, you'll probably love this. If you get dragged to it by someone who loved the play, you won't be bored and will enjoy yourself, even if it won't be your fave of the year.
