Perhaps it's just me being typically strange, but I was hit harder by the end of the 3rd Season. I had to go and lie down in a dark room for a while after that. I think it was a combination of the 4th Season as a whole being largely shite, and the fact that I knew the final episode was destined to be the last ever, that I was expecting them all to get killed so the only surprise was how it would happen.

Mind you, many years later, I introduced a friend to B7, and when it came to 'Blake' I got to see her jaw well and truly drop. Served her right for being a Star Trek junkie, I thought.
