Great comparison, appearantly the old one was filmed in Laguna Beach with sound (didn’t realize the French and Germans duked it out in Laguna 
OK bad joke but in BW one doesn’t notice! The original really follows the book (which is better).
Comparing All Quiet on the Western Front (2022) with the original 1930 film - YouTube
Have you seen the 1979 version with Ernest Borgnine?
Yes, Ernest is one of my favorite actors. I still really like the 1930 version, it also sounds more authentic in German.
Each one has their own thing going. 1930 and 1979 better follow the book, while 2022 can show things that the others cannot. As following source material, I give 1930 the win
Remarque’s work is a book I have happily read at least a dozen times since junior high and so I was super excited, especially with all the hype around the movie before its release, but I have to say I was really disappointed because it certainly doesn’t even make an attempt to follow the timeline of the book as written, I would say the book serves more of an inspiration to the movie than a roadmap for the script. On the plus side it was beautifully filmed, and the cinematography was outstanding, but as far as following the book, no. I like both the 1930 and the 1979 version much better and for me Ernest Borgnine really captures and projects what I always imagined Katczinsky, “Kat”, would be like in real life. This is a little quirky, but I saw the 1979 version when I was in junior high, about a year after the movie was released, and I grew up in a family that never missed an episode of “The Walton’s”. So, while I think Richard Thomas gives a great performance as Paul Baumer, as a kid I couldn’t wrap my mind around “John Boy” as a WWI German soldier. There are a lot of great movies out there about WWI, but Peter Jackson’s 2018 project, “They Shall Not Grow Old”, currently sits at the top of my list, even though it is not a movie in a traditional sense it changed my perspective of WWI like nothing else, because of its realism, giving one an up close and personal feel to what it might have been like to be there. One thing that totally blew me away was how many young British recruits either had a mouth full of bad teeth or no teeth at all! I would still recommend the new All Quiet movie if nothing else than for the cinematography.
