"Unification" was not the two-part Next Generation episode I expected to follow "Redemption." I assumed - and I think a lot of others did as well - CBS-D would continue to release the cliffhanger two-parters as standalone releases. When Season Five was announced I fully expected the standalone release to be "Time's Arrow." "Unification" makes sense, though. Not only does it feature Leonard Nimoy - on the heels of his cameo in Star Trek Into Darkness - it also features the late, great Mark Lenard.
Just like "Best of Both Worlds" and "Redemption," "Unification" features the original episodic promos and a documentary titled 'From One Generation to the Next.' There's also a deleted scene and audio commentary. The 30-minute documentary features commentary Patrick Stewart, Gates McFadden, Michael Dorn, Denise Crosby, Rick Berman and the Okudas to name a few. "Unification" also marks the final appearance of Denise Crosby's character, Sela, which I thought was a bit of a waste.
As with previous releases the HD upscale is fantastic, both in audio and video quality.
