Once again, we see the improvement in so many aspects of this production: more of Jeffrey Green (always a good thing IMHO) and a nice little character twist. I sometimes get a little annoyed with the implication that everyone on a starship had a perfect Academy record, never had personal problems, never underachieved, etc, etc. Maybe that's why I enjoyed the Barclay and Ro episodes of TNG.
Anyway, the sound problems with the first few lines of Grigory's dialogue just can't be overlooked. Just my opinion, but I really don't think it should have been released without addressing that issue.
Aside from that one very noticeable glitch, a sure-footed episode that does a good job of fleshing out a character.
