I don't know. As a first-generation fan, who grew up watching TOS during its original run on NBC and later in syndication, I wasn't comparing it to later Trek shows and movies back in the 1979, since all of those had yet to exist. And I still thought TMP, for all its virtues, felt more like "2001" and "Close Encounters" than the show I devoured back in the sixties and seventies. (For the record, I was in college when TMP debuted.)
And let's be honest here. There was plenty of action and adventure back in the classic original series; heck, Captain Kirk got into a bare-knuckled fistfight every third episode and there was no shortage of colorful space-opera coolness: a lizard monster, a salt vampire, Apollo's giant green hand, and so on, along with the morality plays, topical allegories, and frequently thought-provoking SF notions.
Don't get me wrong. I'm not saying TOS was just fun and excitement, but let's not pretend that it was a purely "cerebral" enterprise that never, ever indulged in good, old-fashioned thrills, chills, full-blooded, emotion, conflict, and drama. The TOS I remember was brash and bold and, yes, even melodramatic at times. Not coolly philosophical
I respect TMP's ambition, but am no hurry to watch it again. Give me Khan or the whales instead.
(Let it noted, however, that I am a big fan of many of Robert Wise's other movies. Not just The Day The Earth Stood Still, but also The Andromeda Strain, The Haunting, The Body Snatcher (with Karloff and Lugosi), Curse of the Cat People, and, of course, West Side Story and The Sound of Music. Actually met Wise back in the day. Still have his autograph.)
