Really unique tv series made in United States in 2013 year. I don't watch many tv series online in Documentary category, but this one was amazing. The Universe season 7 is probably the most known History tv series and it's really entertaining. At all, Documentary can boast of one of the biggest numbers of good tv series. The Universe season 7 is worth watching online, espacially if you can watch it for free here. The Universe season 7 is a a very story, but it has a lot to offer to the watcher.
