I've seen this a few times now, and... I just have to ask, do people like TAS? I'm not one to denigrate a series (I enjoyed the first season of ENTERPRISE!), but, at least in my opinion, every single episode of TAS is worse than any single episode of TOS (with one exception: "Yesteryear"). Give me "The Way to Eden" over "Bem" and "Spock's Brain" instead of "How Sharper Than A Serpent's Tooth" any day of the week. Heck, give me "Divided We Stand" and "The White Iris" (my least favorite episodes of Continues) over "The Counter-Clock Incident" or "Beyond the Farthest Star." TAS is unable to develop interesting science fiction stories, and even failed stories like "Eden" or entirely unofficial, low-budget stories like "Iris" are more interesting than TAS's weekly fare.
And that's largely a function of TAS being so short: it tried to compress the TOS formula (which rarely used the strict A/B-plot separation common in the other series) into half the time by eliminating the Act II exploration of implications and the Act III complication. What you ended up with was flat, boring, predictable, and all at too fast a pace for the viewer to ever properly suspend disbelief.
So when people say that TAS is where fan filmmakers need to look for inspiration... well, that's what led me to my question: do the people who are saying this actually like TAS? Or are we just naming TAS because it's the only thing Official Trek has ever done that approximates the 30-minute guideline?
