Barrera sells the idea that she can absolutely survive, making her resourcefulness in the situation almost plausible. Now we just need to see where the plot goes, which will play out in those flashbacks. ... One of the things we like about the six-episode limited series is that the episodes are all around 30 minutes, so you’re not seeing Liv wandering around the wilderness for hours on end.
Once you start "Breathing," there's a curiosity about how it all turns out, especially since the time demands aren't that daunting. That's not an awful bargain, but if you're waiting for it to get better, well, don't hold your breath.
Where its predecessors were inventive in their approach, Keep Breathing plods along, tediously unrealistic and painfully predictable. You might even find yourself rooting for Liv’s demise in an effort to stir up some excitement.
In all, “Keep Breathing” is, despite some nice moments, fairly forgettable — making its great achievement its willingness not to keep viewers on the hook for hours longer than necessary. Sometimes, that’s impressive enough.
Even if Keep Breathing is entirely Liv’s story, a lot of time is spent on secondary characters so weakly written that none of the supporting performances emerges as even the least bit memorable. ... Barrera has to carry Keep Breathing in a way that no single actor in Yellowjackets has to do, and she nails that level of heavy lifting.
