Star Trek II: The Wrath of Khan
The first movie was a repurposed pilot for a new tv episode, if I recall correctly. It certainly FELT that way. Wrath of Khan was tense, action packed and well-paced.
The first movie was good, but I preferred the second. It had one good solid well-told story and, in many respects was a love letter to long time fans of the comic.
Highlander II: The Quickening
HAHAHAHAHAHAHAHAHAHA! Just seeing if you're paying attention.
