Babylon 5, tail end of Season 2 - Wow. I had borrowed season 2 from friends for a very long time, and decided it was time to return the discs, since I watched the first few episodes a few months back, and never quite got into the swing of watching... but then I said "ok, I'll just watch another episode or two first" and got caught up in watching the end of the show. "Comes the Inquisitor" and "The Fall of Night" still hit me like a brick.
Battlestar Galactica - I'm not sure if I'm disappointed or relieved by recent developments. Either way, the heavy-handed allegory to modern times can please stop soon, maybe.
Doctor Who - the most recent episode (The Girl in the Fireplace) was a good tight bit of sci-fi writing that I enjoyed. I'm impressed with the tenth Doctor, so far; as impressed as I was with #9.
Star Trek, "So How Much For Just The Planet?" - very, very unimpressive. A big steaming pile of fanfic in published form. I wonder what it looked like when read in its actual context.
"Singularity Sky" - neat sci-fi, excellent use of actual physics. Good characters, mostly, though given the implied universe that existed "out there" having the story stuck where it was felt kind of like we were missing out on the best possibilities. I hear there's a sequel; I hope to read it at some point.
Current reading: "Family Tree," Sheri S. Tepper.
