I like the Kazon. They are bit backward, wild and even predictable. They are like sand in humanoid form. Not a lot. That's exactly what I like about them. ST Voyager could instead have gone for far advanced races with big brains, Thor (Marvel) like worlds, and shape shifting space ships. The CGI would have been there. Voyager didn't. Instead, we get several different Kazon sects that each need to make do with alliances. Love it. Those alliances later lead to plots of backstabbing, kidnapping and extortion. To me, all that feels so real, but not unpaid-bills-real. The exact kind of 'real' I want to see, at the far end of our galaxy. Starfleet's Voyager did not get tossed into a far advanced, big-brain, high-tech part of the galaxy - but into literal sand: the Kazon.
