I sort of liked “Spock’s Brain” too.

I do agree that the 3rd season was weakest, especially the last few episodes with one exception which I can’t recall right now

It had clearly run it’s course by then.

Actually none of the episodes were really believable but some were worse than others. For the most part it was best to just ignore things which did not make sense and enjoy it.

One thing which really did bug me was Spock always being anti-racist while denigrating humans all the time. Yeah, I know he was half human.

The 3rd season suffered from a singular problem: lack of money. The network wasn’t happy about its renewal and shorted it on funds. Still, there were plans for a 4th season and it was to prominently feature William Campbell as Captain Koloth.

As the MST3K Theme Song put, "repeat to yourself, 'It's just a show, I should really just relax.'" :-)
