The film has received predominantly negative reviews. Peter Bradshaw from The Guardian criticized the movie for lacking depth in its characters and for a weak storyline, with average visual effects. Similarly, Monica Castillo from RogerEbert.com mentioned that while some action scenes were entertaining, the film failed to connect its scenes effectively, leading to a rather boring viewing experience.

On Rotten Tomatoes, the film holds a low 20% approval rating, reflecting the general dissatisfaction among critics. IMDb reviews also show disappointment, with many viewers expressing that the film lacked substance and was underwhelming for fans of the genre.

However, some appreciated the film’s unique visual style, and it’s acknowledged that Anderson made an attempt to build a new fantasy world. Despite this, In the Lost Lands did not live up to expectations, leaving both critics and audiences largely unimpressed.
