Critical reception
In City Journal, critic Ryan L. Cole praised the book along with the rest of the trilogy. He said that Theodore Rex showed the apotheosis of Roosevelt's life in a way that is "epic in scope and vast in detail". The work has also been criticized by others as having “generated no lasting ideas, no new perspectives”.
