No. 3 - The Search for Spock. 1984

The film that proved what everyone knew already: Star Trek without Spock is highly illogical. Although not as well-paced as it's predecessor, The Search for Spock has its moments: the destruction of the Enterprise, the death of Kirk's son and Christopher Lloyds' ridiculously hammy performance as the Klingon commander, Kruge.

The first film to fuel the theory popular among fans that Trek's even numbered films were good, and it's odd numbered ones were, well, not great.
