Critic Reviews for Lethe

Discovery isn't screwing around when it comes to exposing Lorca's inner darkness, which is bringing true edge to the series.

This is good stuff, with a pleasing moral crunchiness - although we seldom get to see the broken Lorca in private.

Despite the fact that there is a "bottle show" quality to this episode... there is some great character development here.

Oct 23, 2017 | Rating: 4/5 | Full Review…

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.

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.

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.

I like Kol; he's the only Klingon character with any pizzazz, and I can totally see the Empire uniting under him.

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.

Aside from a few moments of needlessly obvious exposition, Lethe was a very satisfying episode.

Oct 25, 2017 | Full Review…

It's incredibly disappointing, as this incarnation of Star Trek seems dangerously close to supporting Lorca's point of view.

Oct 24, 2017 | Rating: 5/10 | Full Review…

This week's episode isn't a bad one. But it marks 'Discovery's' most stark departure from its source material.

It was incredible to look at, for one... with sharp dialogue and intriguing connections to continue teasing out in upcoming episodes.
