I disliked the Augment three-parter. The return of Spiner and the supermen were good, but using it to explain the Klingon makeup thing was lame.
I wish that when DS9 did Trials and Tribble-ations, that Worf reverts to TOS-style makeup after they go back in time, and NO ONE notices. Though Worf's "we do not discuss it with outsiders" line was good enough for me.
Why did ENT need to explain it in such tedious detail? Just have some fun and move on. This episode to me was like "midichlorians" in the prequels.
