Just watched "Exile" on Blu - I'd forgotten what a highly enjoyable episode it is. Extremely well directed by Roxann Dawson, it features some excellent set design, and was nice to see Hoshi take the spotlight for a change. I was quite surprised to hear Branon Braga dismiss it as a weak episode in the included extra features.
He lumped it in with "Extinction" - which he described as one of the worst Trek's he'd been involved with. I'd agree "Extinction" isn't great - but there's undoubtedly been far worse!
