Circle is one of the rare forays into the sci-fi genres, complete with aliens, a futuristic setting and advanced technology. Luckily it handles it well and hopefully is indicative of what's to come.
The show runs with two different parts, one set in our present time and the other in the near future - far enough that technology has advanced and to foster the sci-fi but close enough to still be somewhat recognizable. And while it seems like separating a show into 2 parts would be jarring, it works surprisingly well. Both have riveting storylines and characters that immerse you while also dropping clues that tie the two together. And the plot is tightly woven enough to show how well planned it was. And even the alien aspect seamlessly merges together.
The acting is great, with character ticks that are maintained across actors and the roles being played with enough gravitas to sell the premise.
A definite recommend for any sci-fi fans or those that want to try something different. And with a shorter run-time it's a tight but quick watch.
