My patience with Netflix’s new Lost in Space reboot ran out at roughly halfway through its first season. The new series’ action, dialogue, and plot had ranged from serviceable to truly solid up to that point, and I found myself largely surprised by this family-friendly take on sci-fi survival television.

But the custodians of this new Lost in Space, whose first ten episodes are now live on Netflix, aim too high. Gone is the obvious wink-to-camera cheese that made the original ’60s show such an embedded piece of the American TV zeitgeist. In its place, we have a serious family drama wrapped up in a hyperspace landing on a distant galaxy. The reboot’s best moments—and it definitely has some good ones—are about its heartfelt characters. The same can be said for the worst ones.

As a result, a single wave of logic- and rationale-breaking moments take down far too much of Lost in Space‘s foundation. If that sounds like a dealbreaker to you, then the rest of the show’s solid sci-fi world-building, Lost-like character building, and particularly good teen acting may also fail to keep you engaged beyond that same half-season point.
