Critic Ratings: 11
Critics Consensus

Discovery writers effectively invoke disturbing colonialist narratives in "The Sound of Thunder" to give viewers a more taut, visceral understanding of Saru and Ba'ul history.

Critic Reviews for The Sound of Thunder

This is all so g--d--- human it hurts - a species consciously reorganising an ecosystem for its own benefit, using technology and violence. Oof.

This was a high concept episode with plenty to say about colonialism and power-not to mention another stellar performance from Doug Jones.

"He is our people," is surely one of Pike's best moments yet, and another Star Trek: Discovery season two moment that feels to tap into the Trek spirit.

The writers have been balancing plot so well, never sacrificing character development in service of the story.

Written by Bo Yeon Kim and Erika Lippoldt, also benefits from the focus on Saru. Jones' performance exudes low-key whimsy on a TV series that's full of uber-dramatic aggro action.

This Ba'ul reveal was a truly chilling moment, absolutely the furthest thing from what I expected.

Putting the unwelcome fast pace to one side for now, episode 6's main storyline plays out beautifully.

Feb 22, 2019 | Rating: 3/5 | Full Review…

This is a mess that's treated as an unambiguous triumph, the worst example yet of Discovery's first draft idea approach to writing.

Top Critic

Star Trek: Discovery returns with a compelling episode that fills in a lot of blanks regarding Saru's background, while also pushing his people into a new era.

Feb 22, 2019 | Rating: 8.4/10 | Full Review…

Did I love it like "An Obol for Charon"? No. But still, I felt like this was a very emotionally-resonant episode, especially when Saru's voiceover discussed Saru's adjustment to living without fear.
