YEP!I finished up Season 4 and I was glad to see that Amazon did a great job with saving this series after SyFy dropped it. Probably the best thing that could have happened to "The Expanse", IMHO. Didn't they say when this first came out that it was "Game of Thrones", but in space?
I have only watched Season 4. Would it make any sense to watch seasons 1, 2 and 3?
Yes I had to start over because I had forgotten what someof the plots were about from SYFY. Just about to finish up season 4 tonight since nothing on TV.It honestly doesn't make sense to only watch season 4. lol You absolutely have to watch seasons 1-3 to learn about the origins and power of the protomolecule, the gates, the various political factions, and how the Roci crew came together. All that will become even more important in season 5 (based on the main storyline of book 5, Nemesis Games, which will be off the hook). Even though the first three seasons originally aired on Syfy, they were made by the same studio, with the same showrunners, and writers. It's amazing what they were able to create with a smaller budget than what they probably had to work with from Amazon.
Story seems to be following my memory of the books.
