Brian Tallerico says that "Sadly, the potential of Echoes starts to drain before the premiere is even over as it gets goofier and goofier in a way that’s not entertaining but frustrating. And then it makes the opposite mistake, over-explaining everything about its story through dull flashbacks and interrogation scenes." He adds, "For four episodes, Echoes defiantly makes almost no sense."
A user named "The S" gave Echoes a 1/2 star review writing "Holy cow, er…um, horse. This is godawful. Embarrassing. It plays out like a horrible soap opera plot from the 1970s. The acting is atrocious, the plot is laughably unbelievable. Netflix is the kind of unwatchable series that they throw together in a streaming service where it's all quantity and no quality. My apologies to anyone who sat through this…I know your pain."
Joseph l says in his review "People trashing this show, but compared to what is out there, I thought it was awesome. It's a fun show that sucks you in with a lot of twists. Some of the plot twists are corny but it keeps you mesmerized. As I said, with some of the other offerings in tv watching, it was actually a pretty good show."
