Please mind the #wineposting tag. Regardless: are you asking, "Should I watch this adaptation of Les Misérables?" I'll give you advice, though I suspect if you are reading this blog post you have watched all of these anyway (and quite possibly a few more, besides!).
'25 (Fescourt): Probably! If you are a Brick fan none of the adaptation choices will startle you, but having visuals to go with key scenes is a treat. This is a loyal piece. Toulout as Javert, Gabrio as Valjean, Milovanoff as Fantine, and Nivette as Éponine all give excellent performances. Be prepared for a lukewarm Cosette. You might struggle with silent film conventions, length, and French intertitles.
'34 (Bernard): Probably! This is a fairly loyal adaptation of the Brick that makes internally consistent choices where it deviates from its source (sometimes it has goofy continuity errors—politely ignore). Baur as Valjean and Gaël as Cosette give fabulous performances. Moments of silliness do not detract from the quality. Another long haul.
'35 (Boleslawski): Probably not. As an adaptation of Les Misérables this film is bad. That being said, Charles Laughton is a lauded actor, and you can't say he didn't put his whole laughussy into his performance. Because it is accessible and prominent, a lot of LM fans will have seen this film, and you might benefit from shared context if you're in fandom. Speaking personally, I'm glad I saw it, but I'm not sure you will be.
'52 (Milestone): No. Most likely based on '35 rather than on the book, this film is also a bad adaptation of Les Misérables. There are no notable performances. Because it is accessible, this is another adaptation many fans are familiar with, but understanding jokes about Valjean's boyfriend Robert and Javert's sentient hat probably don't justify sitting through the movie.
'58 (Le Chanois): No. Not the English dub, at least. "Bland" is the word of the day. Contemporary French audiences wildly disagree with me per Wikipedia.
'72 (Bluwal): Strong maybe. If you are an intense fan of the Brick, yes. Its use of a narrator to draw from the novel directly and its focus on the Amis makes this adaptation unique on this list. You might not end up liking it but you will have had an experience. If you have zero investment in Les Misérables but are still reading this post for some reason: no, do not watch this.
'78 (Jordan): At some point I will talk about this film and not make a gay joke but today is not that day. If you are not queer, get off my blog, you cis straight, begone. Everyone else: yes, watch this movie, c'mon. Perkins. That performance. At some point I need to make a serious post about queerness and '78 but right now all I've got is Javert's literal on-screen boner. Jesus Christ. Not a great adaptation of the novel but a virtuoso example of unintentional homoeroticism.
'82 (Hossein): No. This is an odd little adaptation without the charisma of a '35 or '78, somehow not as bad as either of those but not as good either. The GIF of the Amis walking in heavy wind is the best this film has to offer.
'98 (August): No—but I stared into my wine glass for a long, long time before typing those two letters. If we are judging adaptations by how they handle the source material, this is a disaster. As a film? I'm sure entertained. I call it bitchslap Les Mis. I should note here I am also a huge fan of Uma Thurman. Possibly I should recuse myself. I don't know, pal. IDK.
2012 (Hooper): I dwell bitterly on the fact that this is our film version of the musical. Brick fans are restless, musical fans are restless. People who first encountered Les Mis via this version are making feral noises. I'm afraid. I'm moving on.
2018 (Davies): It's really unfortunate that I am at my most drunk while commenting on this adaptation. Sure, watch it, it's one of those BBC series that has watchability sheerly because of production value and proximity to contemporary narrative/film expectations/standards. Personally I hate it. My partner is so tired of the tone in which I utter the syllables "Oyelowo".
The Musical: yes c'mon. Bootleg that good bitch.
