The first 3 seasons were fantastic, last 3 seasons lost their way a little bit, I think SYFY had a better handle on the direction of it. The pacing felt better in the first 3.
I really hope they make the last 3 books, the stage is set for an epic conclusion, it feels a little unfinished, and I believe they did a good job at leaving it open for a finishing run.
I hope they go back to this series and finish strong, the last 3 books are where all the meat is at.
It's definitely worth watching, it's beautifully made. The politics in it are a little quirky, you see a mix of ideologies that actually exist in the real world.
The motivations did seem a little off, I think it was a mistake to stray from the source material. However, it was interesting enough, I hope they make the last 3 seasons.
