Critic Reviews for Si Vis Pacem, Para Bellum

Spending significant time on an alien planet, discovering a new alien species, was quite a welcome change of pace, one that invoked many fond memories of previous Trek series. However, it still had a Discovery feel.

I keep saying to not sweat the details of this episode, so let's not start now - but let's do consider that in delivering its funniest episode so far, STD also delivered its best. Let's hope the creators take that lesson on board.

The Klingon story moved in ways I didn't expect.

... as it is not sure what it wants to be (a landing party adventure, build up for the "climax" of the war or an interesting way of presenting subplots) it makes difficult to really become invested in what's going on.

The intensity didn't let up throughout the episode, and it was a wild ride from beginning to end.

Saru is an angry being, and I think we as audience members - and the members of the Discovery - fail to remember that to be in constant fear is also to be in constant anger.

We did find out more about who some of these characters are, what they want, and what they are willing to do to get it. At least I think we did.

The most recent episode was the first one for me that actually felt sort of like old-school Star Trek. Not that the other episodes were bad or anything, or felt that much out of character with the previous series.

It's a bit of a placeholder episode for Star Trek Discovery this week via a self contained story with no larger ramifications other than to set up the finale. That said, it poses plenty of interesting questions.

If this episode proved anything, it's that Discovery is willing to go weird when it comes to its forms of wonder.

'Si Vis Pacem, Para Bellum' may have been a choppy episode, but it has led the series into its mid-season finale on a strong note and set up the scene for an epic confrontation between the Discovery and the Klingons to follow.

The series began with a two-part introduction to the war and Burnham. It seems apt that the first arc of the season ends with a two-parter that brings the war's two enemy flagships and Burnham into direct conflict.
