With a leading man you can’t take your eyes off of and an adventure that’ll leave you hovering on the edge of your seat, Nautilus is comfort food at its finest and a classic in the making, one you should force everyone you know to sit down and watch.

Nautilus is a visually fun, family-friendly new chapter in the story of Captain Nemo, which keeps the action moving throughout its first episode.

“Nautilus” shows the human cost and terrible harm of the Company’s historical power grab. But it’s also a rocking good time, an adventure worthy of its budget, with a set of heroes worthy of our allegiance, attention, and admiration.

Wall Street Journal by John Anderson

“Nautilus” is a hard series not to like, given it has very few pretentions, a devotion to high adventure and a freewheeling approach to killing off characters and twisting the plot—all the while maintaining some fealty to Verne. .... He [H.G. Wells] was also enormously popular. “Nautilus” should be, too.

Embracing steampunk stylings, “Nautilus” is a serialized, family-friendly adventure with decent special effects.

It can be slow at times, which is not inappropriate to a show that takes place largely underwater. But that its structure is essentially episodic keeps “Nautilus” colorful and more interesting than if it were simply stretched on the rack of a long arc across its 10 episodes.

It may stumble in the home stretch – and it could’ve fleshed out the crew a lot earlier – but in the end, Nautilus rights itself. Some boring storylines for the villains can be forgiven when there are giant eels to fight off.

Screen Rant by Sarah Moran

Nautilus is an entertaining enough series, but there’s nothing particularly remarkable that will make it stand out. And in today’s television landscape, that could be its downfall.

New York Magazine (Vulture) by Roxana Hadadi

Nautilus is bold in its changes to Captain Nemo’s story — new monsters, new villains — but imitative to other genre series in execution, and the vibe is a little didactic.

The Telegraph by Benji Wilson

Nautilus barrels along with the best intentions, is at times exciting… but its characters do say some corny old cobblers.
