I do find it incredibly funny, and I find the main trio's [well, quartet's] dynamic really shines through.
Cute! And when Kirk, Mccoy and Scotty just decide to get into fisticuffs with the guards--- It makes me laugh every time XD
I never mind outlandish things like Spock being able to survive without his brain for a while. Sometimes it's fun to just kick back and think, "Yeah, okay. Let's see where this goes." I guess I just don't need an explanation for everything.
I was going to talk more on the misogynistic implications, but I figure that's already been talked about to death. My only two-cents is that I think having the main depiction of pure stupidity be beautiful women is, ironically, ignorant at best and malicious at worst. But that's probably been said a thousand times over, so don't mind me
However, I do not think it is the worst episode...I think it really shows Kirk and Mccoy's care for Spock. And I really like when more attention is given to the bridge operations. The hypothetical tech get's overshadowed in TOS a lot in my opinion.
It's up there with the more socially ignorant ones, but personally I hate Miri more

I'm aware Kirk wasn't
actually interested in a little girl, but the whole crew's behavior around it felt
so contradicting compared to Charlie X :/
Meanwhile "Spock's Brain" is just much more goofy, I enjoy it a lot more. Even if I
am rolling my eye's at the "dumb women" thing.
