If it were just presented as a fun exploration of what 10 dimensions could be, for fictional purposes, it would be... OKish, I guess. But choosing "10" specifically makes people erroneously think that this is what string theory is about, which is completely wrong.
Additionally, it falls into the trap of assuming that curvature requires a higher dimension to curve in, and that nontrivial connectivity inherently requires such curvature, both of which are false and hard enough to explain to people who have not been explicitly taught wrongly already.
And on top of all of that, it perpetuates the faulty idea that "the" 5th dimension, or "the" 10th dimension are sensible concepts, by presenting its particular choice of dimensions to discuss and its particular choice of ordering of those dimensions as fact.
