Been enjoying Foundation so far. Like DotCommunist in the dedicated thread, I'm sceptical of the whole Psychohistory concept, but the series itself looks fantastic, the acting is good, and so far the story is intriguing enough to keep me watching week to week.
I'm also watching Invasion - a ten part series telling the story of an alien invasion from five different perspectives. It looks a million dollars, and it's pretty well done. Two episodes in and looking forward to seeing the complete annihilation of human civilisation play out in the episodes to come (maybe).
