Star Trek: Every Two-Parter Ranked From WORST To BEST

26. Demons, Terra Prime

Demons and Terra Prime often pull double duty for many fans as a strong two-parter in their own right and as Star Trek: Enterprise's unofficial series finale. 

Both episodes represent what was best about Enterprise. As a series, it had the tough task of being the OG prequel, but set far enough back so as not to risk overlap with familiar faces. Seeing humanity's first forays into deep space and the interstellar community, on the road to the Federation, was always a tantalising prospect.

The Temporal Cold War, and time travel more widely, meant that Enterprise was never truly isolated from the future of the franchise. It was the resurgent xenophobia in the wake of the (temporally influenced) Xindi attacks that emboldened the likes of Paxton in Demons and Terra Prime.
