Well, Spock's Brain is better than The Alternative Factor I don't know how people can say that SB is the worst of TOS, when TAF just doesn't make any sort of sense ("he's got the bandage" "no he doesn't have the bandage" "yes he has the bandage!")
I agree with you: Spock's Brain is barely better than The Alternative Factor, because at least Spock's Brain has that psychedelic, trippy late 60s plot and dialogue whereas Alternative Factor is not very good on any scale except for a few choice, melodramatic, over the top moments with Lazarus. But would you say Spock's Brain is better than City on the Edge or Space Seed or Naked Time or Taste of Armageddon? I'm guessing not.
Really? Sending a criminal to jail who is shouting that he'll get even with the guy or the family of the guy who sent him to jail is suppose to be a hook for a future story line? I've only seen that pulled off successfully once and it was in Dick Tracy's G-Men. Otherwise, it's an overused plot device. So in I, as far as Zod is concerned, the scene gave him a send off and really did nothing, aside from maybe pushing from a future "C" plot line of a 1-dimensional character. And really in II, that's what the writers were trying to do, create an A-story from something that wasn't even "B" plot material.
Plus Zod, as I've already mentioned, I found him to be a very 1-dimensional character---he was written as a villain and then given nothing to get us emothinally involved with his story and why he wanted to kill Superman. Even on Smallville, where the producers seemed to be leading the Zod character up to how Terrance Stamp portrayed Zod in II, I found that Zod's backstory was really nothing that I cared about and it really did not transform this 1-dimensional villain into anything more than a 1.5-dimensional villain. To date, probably the one Zod performance that I really got into was the one from the opening of Season 4 of Lois & Clark. But even then, that Zod was still missing something that was not letting me connect with why he was doing what he was doing.
1) What Christopher & That Old Mixer Said
2) Like it or not, Zod made a positive impression on superhero fans. Otherwise, Zod would not have been brought back in Man of Steel or Smallville. Zod has never been a particularly huge factor in the comics as far as I know, with little appearances here and there. Yet, he still seems to creep back into pop culture. Why? Terence Stamp and Superman II.
PERIOD.
