I'm strictly talking about the original cast films, Star Trek: The Motion Picture, Wrath of Kahn, Search for Spock, Voyage Home, Final Frontier, and Undiscovered Country. You can rate them all if you'd like, my list from favorite to least favorite goes 6, 4 & 2 in a tie, 3, 1, 5. Honestly though, with the exception of 5, I love them all.
I'm really bored and I have no one to talk to about this with.
