Lethe Ratings & Reviews
Independent (UK)
Andrew Lowry
This is good stuff, with a pleasing moral crunchiness - although we seldom get to see the broken Lorca in private.
New York Magazine/Vulture
Mallory Ortberg
Star Trek giveth, and Star Trek taketh away, and this week Star Trek leans pretty heavy on the givething. Explanations! Meaningful follow-up! Weirdly inert daddy-daughter hand-to-hand combat by an inexplicable infinity pool!
Entertainment Weekly
Eric Renner Brown
It's as good an hour as the show has produced yet.
indieWire
Liz Shannon Miller
Discovery isn't screwing around when it comes to exposing Lorca's inner darkness, which is bringing true edge to the series.
New York Times
Sopan Deb
Shoehorning Spock in as Burnham's adoptive brother was a questionable move even before Discovery took off -- and it feels even more ridiculous in this week's mess of an episode.
AV Club
Zack Handlen
While it's obvious fairly quickly that the memory Burnham keeps revisiting is going to reveal something unexpected before the end, when the twist does come, it's a legitimate pay-off.
Geeks of Color
María Garduño
This episode was fun and entertaining, and while the war was mentioned and on the background, the fact that they focus more on building characters and developing the relationships between them was what made it my favourite episode of the series so far.
Ars Technica
Annalee Newitz
Star Trek: Discovery has been getting tighter with each episode, but in last night's "Lethe," the show turned a corner into addictively good storytelling.
Slashfilm
Monique Jones
A series about war doesn't allow for much positive learning, and that's where Discovery fails its protagonist and many Star Trek fans who just want some fun exploring in the stars to start their week.
Birth.Movies.Death.
Andrew Todd
I like Kol; he's the only Klingon character with any pizzazz, and I can totally see the Empire uniting under him.
TV Equals
Mark Trammell
All that really, truly matters is if the show is any good. Does it hold my interest? Am I not entertained, as it were? And so far, the answer is mostly yes.
The Daily Dot
Gavia Baker-Whitelaw
Aside from a few moments of needlessly obvious exposition, Lethe was a very satisfying episode.
The Young Folks
Andrea Thompson
It's incredibly disappointing, as this incarnation of Star Trek seems dangerously close to supporting Lorca's point of view.
Cleveland Plain Dealer
Patrick Cooley
This week's episode isn't a bad one. But it marks 'Discovery's' most stark departure from its source material.
Digital Spy
Megan Davies
It was incredible to look at, for one... with sharp dialogue and intriguing connections to continue teasing out in upcoming episodes.
Empire Magazine
Ed Gross
Despite the fact that there is a "bottle show" quality to this episode... there is some great character development here.
Akron Beacon Journal
George M. Thomas
Pay close attention to the last 10 minutes.
Den of Geek
Kayti Burt
It's a shame to see Discovery continue to make these interesting narrative moves without doing the character work and set-up to make us care what happens.
TV Fanatic
Diana Keng
There are certain episodes that I would prefer to just sit back and relax into. This one falls into that category because the driving action is really a slow path to the final rescue.
IGN Movies
Scott Collura
Star Trek: Discovery has found its pace at his point, moving along on a variety of storylines that are satisfying on both a character and plot level.
