Nope. No corn at all, it almost moved me to tears NOW. Then again, my father died a month before it aired, but I don't remember watching this episode at the time. There could be good reason for that, I dunno. Given my reaction to it, my thought is I probably DID watch it then, which is why it moved me now. Maybe.I do remember this episode pretty well, though--I remember it moving me to tears back 20+ years ago. But knowing the overall concept of the episode, I fear it will be really corny today.
This is also the first I've seen Ronald D. Moore's name, and Google confirms... this was the episode he wrote on spec and got him onto the show.
You can tell.
