I love Star Trek v: The Final Frontier.
It has a few bruises, namely the special effects and some of the cheaper humor. At its heart it has a great story and advances the lore more than its given credit for. I really enjoy some of the character moments. People talk smack about the fan dance but I think it's fantastic that an actress in her mid-50s got a chance to show off, in light of how Hollywood back then and also nowadays tends to treat women in that age group. And the use of color, particularly in the latter half of the movie, is simply dazzling. I think it's better than at least 3 out of the 4 Next Generation movies, if I'm being honest.
