Yes, that particular plotline resembles the battle between humans and Cylons on Battlestar Galactica, and it's certainly an easy comparison to make.
There are some brilliant space chases in the first two episodes in scenes that remind of Battlestar's thrilling opening.
But this isn't a simple retread. Those Thrones comparisons come from from an expansive storyline that a Salon reviewer called an "information dump".
"I had to watch the first episode of The Expanse twice, pausing at times to rewind and replay, paying close attention to even interstitial establishing shots," wrote Sonia Saraiya.
"But where Battlestar Galactica's story engine ran almost entirely on mystery, The Expanse is a little more like Game of Thrones, with its intensely detailed and ever-broadening world inhabited by very recognisable characters...
"(It's a) gritty science fiction epic that combines the Earth-centric politics and space-travel details of Star Trek with the wonder and romance of Star Wars."
There's more good news: network SyFy has ordered a second series for 2017, indicating that this is a space war that has only just begun.
