There are more ep's in season 7 that had really out there plots such they I greatly disliked them. This one isn't one of those, but it's not one that I really like either.
Olandt did an ok job, but I was truly creeped out by his making the moves on Troi. In real life their ages are pretty close, but their characters ages are far greater and it just seemed creepy to me.
Again in real life, the Stewart and Olandt age difference makes it possible for a father-son relationship, but for their characters I think by putting together dates and ages over the series makes it a tad unlikely and obviously birth control was used in the future.
It brings back a past adversary and that storyline of itself is ok. So watch it, but you may not like it.
