Echo Valley opens at the bottom of a lake. A wrapped-up dead body is adrift, the details as murky as the ethics of the person who put it there. How and why that body got to where it is is the central mystery that will be solved, unraveled, and resolved within the next two hours.

It starts on Kate's titular Pennsylvanian horse farm (Julianne Moore). Due to her wife's tragically sudden passing earlier in the year, the farm is just downtrodden as Kate's emotional state. Doing the bare minimum to keep the place at least somewhat presentable is the only thing that gets her out of bed in the morning, which takes a little longer to accomplish with each subsequent day. A barn roof collapse doesn’t make matters any easier, forcing Kate to beg for the $9,000 to repair it from her ex-husband Richard (Kyle MacLachlan), who now has a much younger wife and daughter. The two of them share an adult daughter named Claire (Sydney Sweeney), who's been in and out of rehab several times over and is relatively estranged from her parents.

While Richard has stuck to the pledge they made in family therapy that they wouldn't interact with Claire until she got better, Kate can't completely go cold turkey. A few days later, Claire shows up at the farm. She still has a shitty boyfriend, but things seem to have drastically improved. That is, of course, until it's revealed that she has gotten involved in a drug debt and has no one else to turn to except for Kate.

I'll stop the plot synopsis there to preserve the cover of who that dead body is, and how they got to be there. The script comes from Brad Ingelsby, who most recently created and wrote every episode of Mare of Easttown, alongside films Out of the Furnace, The Way Back, and American Woman. The pervasive themes of strained familial relationships within a crumbled America are present here, just in a frenzied manner. Stories like this have become dime-a-dozen streaming miniseries at this point, and there are more than a few instances here where that route would have lent to a more methodically structured story. Twists and turns come at a pretty rapid rate, leaving little time to question what's going on and how we should react. Then again, it's nice to watch a story dole out multiple swaths of information in minutes rather than chunking it out over several hours.

Having great actors like Moore and Sweeney at the helm helps make it all go down more easily. There are years of melancholy in each of Moore's choices, grounding the highwire choices she has to make as a parent. Despite not being present for large stretches, Sweeney makes the most of her opportunities. The frenetic energy she brought to her character in Euphoria is replicated here. A harrowing confrontation between mother and daughter becomes the standout scene, as each character unloads years of baggage on the other. The subsequent busyness of the plot loses focus on that raw emotionality, almost as if Ingelsby doesn't trust himself to reach the audience without a tried-and-true murder plot.

Director Michael Pearce, the main discoverer of Jessie Buckley with Beast back in 2017, shoots this story with a gloomy palette. There are moments where it feels as if he didn't know that the final product would be watched on Apple TV+, with the overall darkness of the imagery requiring a pitch-black cinema to make out any of the details. On one hand, I blame myself for watching this on a summer afternoon, the sun being too powerful for my curtains. On the other hand, I lay some blame on an artist for not being considerate of his audience. It's that kind of dichotomy stretched across each department keeping this film from lifting itself out of the realm of being respectably average.
