I think that the most overwhelming feature of Romanticism in the film is the reveling and embrace of imagination. Barrie's relationship with the children is predicated upon the ability to imagine and to envision a world that is so diametrically opposed to reality. This is Romantic in a couple of ways. The first is that it worships at the altar of the subjective. Romantic thinkers believed that individual voice was essential to consciousness. Barrie represents this as his time with the children is driven by the imagination that he and the children share. Another Romantic element present is the idea that individuals do not need to conform to their social setting around them. Barrie and the children are not acting in the manner that society deems appropriate. This is another trait of Romanticism in that the movement sought to make individuals different from the conformity and homogeneity of thought which had a hold on society.
