The seasons with Mutiny were a real treat, great hacker startup energy and a really fun exploration into the new tech frontiers that were opening up at the time. The overall story did end up weird, but it's one of those shows where you're free to just view the characters as vehicles into a compelling world.
This is IMHO true of H&CF.
It is also true that part of this was the pivot to foreground the female characters (1)
The idea that the show was "ruined" by not portraying them as just "hot chick" and "wife" is a) extremely gross and b) a statement that's really only about the person making it.

As a counterpoint, I really enjoyed Dog Day Afternoon, which is basically a masterclass in taking a single situation and a fantastic actor and just letting it play out.
