This series has some good content, but I felt that the quest to be "epic" in the frequent heavily scored recreation scenes tended to overwhelm the content a bit. I thought that it was fine that the series attempted to try and create a sense of awe and monumentality about some of the moments it purported to depict, but I just wonder whether there should have been less of it. The cinematic power of some of those scenes was great, that said.
Nevertheless it was enjoyable and at least moderately informative. Anyone interested in human evolution will probably get something out of the series, if they don't mind the frequent dramatic interludes. In an attempt to reach a bigger audience though, it's pretty clear that the BBC has sacrificed a little of content potential of the series.
