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.
It is on archive: https://archive.org/details/MASH-Complete-Series — I haven’t watched it “Without Laugh Track” that might be a different experience.
