Despite the Vulcans' presence as official allies, Archer often comes into conflict with the Vulcan High Command; at one point, Archer must battle to keep his science officer on the ship.
The tension is ratcheted at season's end as a shocking attack on Earth threatens the species and alters the Enterprise's mission.
The Season 2 Blu-ray features multiple commentaries and behind-the-scenes featurettes; the episodes themselves are presented crisply and cleanly. “Enterprise” was the first “Trek” to be shot in HD, and the picture quality shows.
