I made it to the first episode of Season 3 last night. Then I got tired and had to stop.I did that same thing while I was writing Babylon 5 season 2 reviews for my site.
I ended up getting carried away and continued binge-watching season 3. Before I knew it I'd gotten through all 5 seasons before I'd published my review of the episode Knives. Don't make my mistake!
Luckily the final three episodes of Season 2 are distinctive enough that I can separate them in my mind when I write the reviews. I'll have to re-watch the first episode of Season 3 though, when I write the review for it, because it won't be fresh in my mind anymore by the time I get to it. Great start, though!
I think the third season is going to be my favorite thus far.
I've also got it mapped out in my mind that I'm going to get up to the 88th episode of DS9 and 55th episode of B5 during the same day/week. It'll be a huge milestone in this journey, because I'll be exactly half-way through both series. The middle of Season 4 of DS9 and the middle of Season 3 of B5. Time flies!
