Two of the Battlestar Galactica webisodes are up on scifi.com now. They're not badly done, but seem to suffer from the two-minute format. The long-format show crams a lot into forty minutes. Splitting it up so sharply might be making it hard to build the tension (some might say melodrama) that has been a trademark of the series.
From a futurist standpoint, the webisodes (a neologism I find less annoying than I thought I would) are a good mid-point between a typical Web non-presence and the in-depth obsessiveness of Lost's alternate reality games. Galactica has been good about rewarding fans online for a while, with the commentary podcasts and video blogs. Clearly it takes a lot of work to put these together, and I hope it pays off for them.
From a storyline standpoint, there seem to be a few callouts to civil war in Iraq coming up next season. Specifically, I'm thinking about the resistance infiltrating the Cylon police and hiding weapons caches behind religious icons. How much is coincidence and how much is intentional? That's never an easy answer with Galactica, which featured a torture scene with waterboarding in its first season. I'm looking forward to seeing if Ron Moore has anything to say about it on his blog.
