The Voyage home is probably my least favorite falling down my personal rankings over time of the original cast movies although I can still roll with it. TMP and 'Khan are at my top. I will watch all six movies in chronological order when they come out and likely sell off existing UHD BD boxset...
My older brother who is a big Trek fan, and saw TMP in 1979 while he was in high school, thought the 2001 Direction Edition version was an improvement when we watched it on DVD. He also owned the longer version VHS.
