THIS is Epic Science Fiction
27 July 2018 | by ianhyhu-176-173937See all my reviews

I knew that the season 3 finale for The Expanse was going to be good, so I prepared a large bowl of popcorn and a can of my favorite soda for a Friday night treat. But I didn't know it was going to be AMAZING; I left my popcorn and soda untouched because I was glued to the action, and now I am writing this review immediately after viewing.

The scope of this episode promises a 4th season which will certainly take hardcore science fiction series to a whole new level, with the pacing, acting, soundtrack and CGI to make us feel like we are taking the journey with the protagonists in a futuristic universe.

And what a journey it is; the episode is ambitious in scope and pulls off nearly every question it tries to answer: How much can a person adapt under duress (applied to thousands of people stuck in the Ring)? We see alliances change rapidly, and characters experience life-altering epiphanies in the midst of an unfamiliar, alien space.

For those who want to get into the series, now is a good time. For me, this episode was one that tied off everything that happened so far; all the characters and plotlines that have been introduced have been leading up to this critical moment. You won't be disappointed!
