The issue about getting a fans perspective on the Kazon is that said fan has to remember the Kazon. They were incredibly forgettable.
Voyager takes place tens of thousands of lightyears away from Federation space. The whole plot is them trying to find their way home while running into new alien species. Vulcans, Klingons, Romulans, Ferengi… all that is gone and we need to start over. So they go back to the drawing board to make a bunch of new alien species for the show. One of the main ones being Kazon.
They were seemingly designed to be a hostile faction that really liked war. They had forehead ridges, jagged teeth, a very particular hair style and their skin color was predominately darker. If that sounds familiar it’s because it’s basically just the klingons. Only issue is that these guys had none of the history that the Klingons did. Just Klingon Lite. Also didn’t help that they were wildly misogynistic. The society was entirely patriarchal so women were treated as second class citizens.
They lasted two seasons. The last time we really saw them on screen was the first episode of Season 3. Anything since have been passing references.
They were just kind of a lazy, badly written species that had nothing going for them and are best left relegated to the scrap piles of history.
