One of my top 10 TNG episodes; I've always considered it a vastly underrated and oft-forgotten gem.
I've been enjoying MEG's TNG reviews (generally), but agree with others who believe she completely missed the point of this episode, especially the ending. She's seeing it as far too black and white, though at least she seems to admit that in her closing lines. Kevin's confessional scene is heartbreaking and still brings a tear to my eye even after a dozen viewings thanks largely to the actor's devastating performance. He is clearly not an evil man; he made a mistake, albeit a grave one, in a fit of temporary insanity caused by his passion and love for his wife. It's tragic, sad, and beautiful all at once.
