2, 4, 6, 8, who do we appreciate?
The thing I like about the 4 good ones is they are actually really different films. Not many franchises can say that.
Khan, is the hero / villain archetype with both the protagonists chewing the scenery
Voyage Home, is just a daft caper with the cast clearly enjoying every minute, I still love Scotty picking up a mouse “Hello Computer”
Undiscovered Country is basically just a stand alone who-dunnit film. With added Sulu as Captain of his own ship.
First Contact is pretty much a straight up action film “Prepare for ramming speed”. Although Picard misquotes Melville, but I’ll forgive him.
