The one thing that the 100 has done perfectly over the past 6 seasons is character developments. The main characters have had so many ups and downs and sometimes we did hate some of them but overall we love them no matter what and frankly they are the only thing that make the 100 a great show.
In this season, however, after 9 episodes we haven't seen any of them do anything amazing yet. I mean, we want Clarke, Bellamy, raven, or Octavia to at least be a part of something in this final battle. Speaking of which, we dont even know exactly what it is and just hear the bardo people talk about it.
I believe the storyline of season 7 is brilliant in general but they have somehow failed to show it in the amusing ways they used to. It took me 9 episodes to be interested in the sanctum storyline which could have been wonderful from the start. And the bardo storyline is starting to piss me off. I need answers. I hope they dont uncover everything only in the final two episodes. Especially Bellamy's plot.
All in all, I still love the show and believe it is one the greatest ones I've ever seen. I just hope they dont mess up the series finale and the next 7 episodes be much greater than what we expect.
