Part of a Franchise?...
Star Trek II: The Wrath of Khan is the second of six movies to star all of the main Star Trek original series cast, and is a direct sequel to the series episode Space Seed. It also begins a trilogy of linked films in the franchise, and is the first of two Star Trek films to be directed by Nicholas Meyer.

Watch or Drop?...
The Wrath of Khan is generally considered as being the best Star Trek movie. It's not my particular favourite, but I consider it as being a great sequel to Space Seed, and definitely rate it as being one of the more essential Star Trek films to watch. Definitely watch Space Seed first, then read the Ruling in Hell comic run, which fills in the gap between that episode and this film.
