Well, I'm just more into defending the movie against statements of "it's nothing like the original series", because it is like the original series.
I don't understand this argument at all on either side. Just because it's like the worst episodes of TOS doesn't mean it's like TOS.
By this same logic I could argue Insurrection is the best/worst TNG movie because it's most like the worst episodes of the show: bad love interests, dull pacing, sanctimonious preaching, poorly thought out morality plays. Because that's all that TNG was, right?
well to be fair, not all those who defend TFF as being in the spirit of TOS mean it as a dig at TOS' occasional bouts of campiness, cheesy humor and special effects, etc.
They might also mean it's like TOS because of it's exploration of the Big Three, it's plot bringing up the Big Questions, etc.
Yet I mostly agree with your point. If TFF was a TOS episode, it'd most likely be a weak, season three episode.(Hey, it already kind of was with "way to eden.")
