Loved it from the start to end(if this is the end with so much good material still to draw on) and it is a show that benefited hugely from having the authors on hand to keep it true to the source, the vast majority of the changes felt like logical choices based on the medium and time constraints, or alternatives that the authors might have chosen. Very rarely did it feel like the usual Genre TV writer self insert berating the viewer with a message. Not that The Expanse was apolitical, far from it, more that they did it in a way that rarely broke immersion and ran in step with the plot and characters.
We need more great Sci-Fi, so much story telling potential in the genre, and there is a vast amount of superb work out there to adapt if the original ideas are not there. However I look a show with the quality of The Expanse scraping and struggling from Sci-Fi to Netflix to Prime and it disheartens me. This show could have been Game Of Thrones for Sci Fi, crossover appeal, making the genre commercially viable with a load of other shows trying to take up the slot. Doubt it will happen. Look at this thread, 14 pages in 6 years for a show of this quality.
