Watched it all. Begins as interesting Jules Vern type story, but episode 23-34 (island & Africa) are awful. Last 5 episodes return you to a great story. Probably the greatest example in drop in quality I have seen to date. Strongly suggest just reading summaries for terrible middle part. You have been warned. Likely 1 to 2 stars higher if it wasn't for the middle.
