Todd Russell’s review published on Letterboxd:
Gemma (Imogen Poots) and Tom (Jesse Eisenberg) take a tour with a real estate agent inside the Yonder home development. After showing the house and letting them into the backyard the eccentric agent leaves. Upon realizing he took off, they attempt to leave the housing area, only to end up back at House #9, the same house they were shown. Soon, deliveries show up with essentials to keep them alive, but there are no other people until an odd young boy shows up to live with them.
This seems heavily inspired by that old Twilight Zone episode "Where is Everybody?" only it's involving a couple in a housing area instead of one person in a seemingly abandoned house development. The boy makes load screaming noises and acts very strangely, as if the couple are his parents.
The movie was a bit long and meandering to get to the payoff, which without spoiling, wasn't as satisfying as it could have been. This would have worked better in an anthology show at maybe 45 minutes max length. Just OK otherwise and not recommended.
