I remember seeing bits and pieces on broadcast television as a child. About 10-15 years ago I downloaded it and watched it except for the very end; it became intolerably bad eventually.

I'm just in the first seasons this time round.

Misogyny, in particular (but not limited to)removed culture, is a notable comedic theme.

Later, the character Klinger who is pretending (? over emphasizing) to be crossdresser to evade military service adds trans misogyny as a comedic theme.

There are undertones of racism, colonialism, anti-communism.

On the upside, there is a pervasive liberal humanism. MASH was thinly veiled metaphor using the Korean war for the contemporaneous Vietnam war. It was ostensibly anti-imperialist, and anti-American. It's hard to write anything apologetic here, but it doesn't all suck.

I haven't watched it "Without Laugh Track" that might be a different experience.
