Frank Turtletaub’s review published on Letterboxd:
Beautiful world building and great film set the stage for a decent plot. The fantastical moments of this film are obviously the best and honestly make it worth watching just for them. Baquero does a great job and we wonder along with her about the mysteries contained within the labyrinth itself.
It seems as though the film is trying to say something about childhood innocence and the ways they are effected by them but ultimately the two points never seem to be juxtaposed and reveal themselves early on with no further elaboration.
The Civil War sections are decent enough but they don't really add as much to the film as the fantastical points do--they seem to be a bit more repetitive and overall mundane.
It's worth a watch for the imagery and design alone, but those unfortunately lacking parts don't hold up much under scrutiny.
