Watched "Pen Pals," and I gotta say this ep looks amazing in HD. Especially with the Holodeck scenes in the countryside, and all the dramatic closeups of the actors. And it looks like HTV actually got the Enterprise right this time (although Sarjenka's planet is sadly a bit hazy and out of focus).
And watching this season for the first time in a while, I'm finally starting to appreciate Pulaski more as well. I remembered her always being kind of cold and unlikeable, but she actually warmed up quite a bit as the season went on. In fact her scenes and dialogue in "Icarus Factor" were probably the best part of that episode.
