It’s so sad that women (including one of my relatives) put up with that treatment. I’ve read that Spector paid his ex-wife Ronnie her alimony in bags of nickels.
They absolutely have, and I’m sure there are 10,000 posts on this site alone criticizing them for their transgressions.
Criticizing appearance is normally odious. Normally is not universally. In a political climate in which loud voices on the right say that women should be subservient to men, should be attractive to men, should stay at home, but shouldn’t vote and shouldn’t run for office, the fact that the right fetishizes and promotes women who conform to appearance standards promulgated by white supremacists/Christian nationalists/neo-Nazis and similar groups requires us to recognize that this is not a mere coincidence on a trivial subject. It’s deliberate and symbolic and serious.

Anybody else ever wonder if Andy Taylor, Jed Clampet, Steve Douglas, Bill Davis and Eddie’s and Gidget’s fathers ever got together and compared notes about how they killed their wives?
They were all inspired by Adam Cartwright.
Mike Brady too.
Ben Cartwright
Him, too
Or Atticus Finch
(But not Harper Lee’s actual parents. Her mother was very much alive, but suffered from bipolarism.)
Carol’s first husband, though, while presumed dead, was actually still alive on an uncharted Hawaiian island.
In an 1970s-unmentionsble relationship w Gilligan, the Skipper, or worse yet both?
Three-hour tours can be life-changing experiences. 
Actually, wherever the home of operation for the Minnow was, what would there have been worth seeing for three hours?
A month-ish ago I took a 3-hour boat tour along the coast in Costa Rica. We probably covered 8-ish miles up-coast and back from the harbor. Pretty scenery, pretty water, several nice inlets & beaches and 3 stops to snorkel. There were islands in range of our trip, but certainly nowhere uncharted where a boat could be visibly shipwrecked on a beach with no search and rescue follow-up.
TV: reality with most of the realism filtered out.
My favorite fanwank is that Gilligan’s Island takes place in the same fictional universe as My Favorite Martian, Bewitched, and I Dream of Jeannie, where the constant use of preternatural power has weakened the fabric of reality. The Island being an irresistible magnet for anything floating in the ocean off Hawaii might be a mere side effect of some joke Uncle Arthur played for example. Also see Green Acres.
Shows like these were killed off in the early 1970s. This happened around the same time as the “rural purge”. So there was also a “fantasy purge”:
I’m pretty sure with Mary Ann.
(and yes, the show did actually allude to her first husband having been The Professor).
It’s somewhere in the Hawaiian chain. And the island they landed on wasn’t anywhere near any of their intended sightseeing locations. The storm blew them pretty far.
(and yes, now that @Lumpy mentions it, maybe into a different dimension)
Carol was in a relationship with Mary Ann Summers before she married Mike Brady? I guess that explains why she only had daughters.
Six strangers on a train would be even harder for the police to unravel
No, Carol’s ex was in a relationship with Mary Ann.
No, I believe Carol and Mary Ann became friends in Salina, and over time their friendship became intimate (the wickedness of it added extra spice), so when Mary Ann turned 18, they moved to Lamar, which was just laid back enough to tolerate them but still enough like Kansas to be comfortable.
Carol bore 2 daughters by the ampoule, then Mary Ann had Cindy that way, and when Cindy was about 2 years old, the whole family managed to take a vacation in Hawai’i.
Carol did not feel like going on the 3-hour tour, so she took the girls to the beach. When the Minnow was lost, she waited for Mary Ann to come back, taking a job in a local steakhouse to support the family. Mike took frequent trips to Hawai’i, both for pleasure and for work, and stopped at that steakhouse often.
After years of waiting in vain for her lover to return, Carol accepted Mike’s offer of a home back in LA, and found that escaping the sad association that Hawai’i had become for her was a tremendous relief.
And, of course, marrying Mike allowed her to obfuscate the origins of the children. Mike knew all about Mary Ann but kept it quiet because he truly loved Carol and to be honest, thinking about it turned him on. The girls were young enough when Mary Ann disappeared that it never really registered with them that there was anything particularly unusual about mom’s previous relationship.
