Dekker had several qualities which made him a desirable coadjutor in play-writing. He was a master of the craft of the stage. A man of quick sympathies, unconquerable buoyancy of spirit, infinite readiness and resource, he had lived among the people who filled the theatres, and took a genuine delight in moving thereby the exhibition of common joys and sorrows. His whole heart went with his audience, and, though he had not the loftiness of aim of his greatest contemporaries, none of them had a finer dramatic instinct. He knew London as well as Dickens, and had something of the same affection for its oddities and its outcasts. The humour which lights up its miseries, the sunshine which plays over its tears, the simple virtues of the poor and unfortunate, patience, forgiveness, mirthfulness, were the favourite themes of this tenderhearted dramatist. His plays are full of life and movement, of pathos that is never maudlin and humour that is never harsh. Vice always gets the worst of it, hardness of heart above all never goes unpunished, but relenting leniency always comes in to keep retribution within gentle bounds. Virtue is always triumphant, but it is discovered in the most fantastic shapes and the least conventional habiliments. It needs some charity to tolerate such heroes and heroines as Simon Eyre, the mad shoemaker, Candido, the patient citizen, Orlando Friscobaldo, Bellafronta, and other types of strangely disguised goodness, but the dramatist's own love for them, with all their absurd eccentricities, is infectious. He laughs at them heartily, and carries us with him in his humour, but he knows how to change the key and soften laughter into tenderness.
Dekker's verse is naturally graceful and copious, keeping unforced pace with the abundance of matter supplied by his fertile invention. He was not a careful writer. He probably "never blotted a line," and one cannot read his plays without wishing that he had "blotted a thousand." His intellect had not the intense chemical energy of Shakespeare's, through which no thought could past unchanged; and he did not strain after originality as some of his great compeers did, Webster, Jonson, Ford, and Chapman. He poured out in an easy stream whatever came readiest, and his best passages do not run far without being marred by some poor commonplace, tumbled out as it entered the mint, without any new stamp impressed upon it. It is in his songs, interspersed at too rare intervals through his plays, that Dekker appears at his best. He had the most exquisite gift of song. Few of his contemporaries had a harder life, but all the miscellaneous drudgery through which he had to toil for a precarious livelihood failed to destroy his elasticity and spirits, and his songs rise from the earth like bird-songs, clear, fresh, spontaneous. There is genuine lyrical rapture in the notes. Like most town-bred poets, he had a passion for the country, and his fancy is never more happy than when dwelling on rustic delights.
