Yeah... it was overused before Voyager and Enterprise got their hands on it. That horse is dead. I swear, it's easier to go back in time 200 years than it is to warp from point a to point b.
On the other hand, just to play chrononaut's advocate, time-travel has a pretty good track record when it comes to generating quality episodes and movies. Many of the most popular Trek stories are time-travel stories: City on the Edge of Forever, Tomorrow is Yesterday, All Our Yesterdays, Assignment: Earth, Yesterday's Enterprise, Little Green Men, Trials and Tribble-ations, Future's End, Timeless, The Voyage Home, First Contact, etc.
And book-wise, you have Yesterday's Son, Imzadi, and other classic Trek novels.
