Eh, why not. I'll give it a shot
Undiscovered Country
Wrath of Khan (nearly tied, but I wanted to break tradition by flipping the order)
Search for Spock
Voyage Home (again, nearly tied with these two, but I again flipped the order)
Final Frontier
TMP (BORING, but at least had the novelty of seeing the characters' lives after Starfleet... before coming back to Starfleet)
