"Dark Frontier" kicks ass in surround sound, especially when the Borg speak. I highly recommended rewatching it that way if you can.I actually watched Dark Frontier on my laptop at school. Maybe I should have watched it at home with surround sound and a big screen for the full impact? Still an enjoyable episode, though.
And about The Disease, there was clearly a good reason to consult the medical officer before engaging in sexual activities. There's no way of knowing what will be passed between two species. Didn't bother me.
I don't mind "The Disease" either.
The protocol seems like a sound one being you're now on the other side of the galaxy. New species, new STD's.
However, it might have been a little more interesting if Harry Kim being the foreigner in the DQ was the one that introduced the STD into their culture instead.
