Babylon Squared (B5) - This was a very good episode. Seeing Babylon 4 reappear was cool. I liked the look of the station, and the fact that its not just a copy of B5. Garibalid and Sinclair's conversation about pants on the way to B4 was pretty funny. D'Lenn's parts were interesting, although I was pretty sure she'd be staying on B5. I'm not sure why having a single space station is so important to the future, but it still made for a good story. The identity of The One was pretty obvious. I bet this will be brought up again.
It is very hard to offer a reply considering hindsight is 20/20, but I will say once you finish at least Season 3, your opinion might be worth looking at again.
God I hope that isn't a spoiler because that is not what I intend to do.
