Even after 50+ years (30+ for me personally) TOS remains the pinnacle of Trek for me. All the other series have highlights and their merits for sure, but there is just a visceral love of the series through and through no matter the episode. I attribute this to obviously the performances, ideas, characters, and writing. Though I also believe the color pallette and especially the music appeal to the eyes and to the ears more so than the modern iterations. Exposure since a young age from beta TV recordings to Blu Ray quality have reinforced this feeling over the years. At 34 years of age, I wonder how many others my age feel the same, what with all the alternative forms of entertainment options out there.
