Althoug I thought the concept of a parelle universe in which Worf and Troi were married was interesting, they should've ended it with that. Troi's visions in "Eye of the Beholder" was a bit rediculous and having the two of them together in "All Good Things..." was a big mistake. Troi has always worked better in the series with Riker. Worf and Troi's characters are so opposite, I suppose that's why they thought a romatic relationship between them would be interesting, but it wasn't, it was stupid.
On the bright side, the writers seem to realize this, by forgetting it ever happened. Worf moved on with his life on Deep Space Nine, and in "Star Trek: Insurrection" Troi is back with Riker. Worf even made a comment in that movie, basically giving their relationship his blessing.
