I disliked this ep very strongly. I enjoyed the opening scene with Riker cooking because I thought, "hey finally some character development." But Riker made some silly, erroneous conclusions of logic--which Picard tragically heeded. The ship was in danger and Picard's ridiculous sense of curiosity (encouraged by Riker's shaky "you can't change the future" crap) overruled gut instinct to call ALL STOP, COME ABOUT AND WARP US THE HELL OUT OF HERE. Troi was utterly useless, as it was not hard to determine Crazy!Picard's state of mind. Just look at the wild eyes! Apparently in the future we stop observing body language so the token hot chick can read minds instead?
Head straight into the vortex, yeah that made sense.

Even Q couldn't have saved this ep, and knowing his flair for the dramatic, there's no way he could have done this without telling everyone on the ship (twice) that he was behind it.
Scifi needs to hurry up and get on to seasons 3 and 4, where we get some great characters and better executed plots
