I don't know how I started to watch ... But when I started , I fell in love totally.... It was damn good series, love it whole session ... From 1 to 5 season it was totally realistic but after that 6-7 it was like imagination..... But this series gives lots of lessons about earth that we do not harm in anyway.... And the ending was superb... Thanks 100 casts... And director, and with Raven I just fallen in love with her ... She was so strong in every situation.....❤️
