We do not like to see our author's plays acted, and least of all, Hamlet. There is no play that suffers so much in being transferred to the stage. Hamlet himself seems hardly capable of being acted. Mr. Kemble unavoidably fails in this character from a want of ease and variety. The character of Hamlet is made up of undulating lines; it has the yielding flexibility of 'a wave o' th' sea'. Mr. Kemble plays it like a man in armour, with a determined inveteracy of purpose, in one undeviating straight line, which is as remote from the natural grace and refined susceptibility of the character as the sharp angles and abrupt starts which Mr. Kean introduces into the part. Mr. Kean's Hamlet is as much too splenetic and rash as Mr. Kemble's is too deliberate and formal. His manner is too strong and pointed. He throws a severity, approaching to virulence into the common observations and answers. There is nothing of this in Hamlet. He is, as it were, wrapped up in his reflections, and only THINKS ALOUD. There should therefore be no attempt to impress what he says upon others by a studied exaggeration of emphasis or manner; no TALKING AT his hearers. There should be as much of the gentleman and scholar as possible infused into the part, and as little of the actor, A pensive air of sadness should sit reluctantly upon his brow, but no appearance of fixed and sullen gloom. He is full of weakness and melancholy, but there is no harshness in his nature. He is the most amiable of misanthropes. THE TEMPEST. There can be little doubt that Shakespeare was the most universal genius that ever lived. 'Either for tragedy, comedy, history, pastoral, pastoral-comical, historical-pastoral, scene individable or poem unlimited, he is the only man. Seneca cannot be too heavy, nor Plautus too light for him.' He has not only the same absolute command over our laughter and our tears, all the resources of passion, of wit, of thought, of observation, but he has the most unbounded range of fanciful invention, whether terrible or playful, the same insight into the world of imagination that he has into the world of reality; and over all there presides the same truth of character and nature, and the same spirit of humanity. His ideal beings are as true and natural as his real characters; that is, as consistent with themselves, or if we suppose such beings to exist at all, they could not act, speak, or feel otherwise than as he makes them. He has invented for them a language, manners, and sentiments of their own, from the tremendous imprecations of the Witches in MACBETH, when they do 'a deed without a name', to the sylph-like expressions 'of Ariel, who 'does his spiriting gently'; the mischievous tricks and gossiping of Robin Goodfellow, or the uncouth gabbling and emphatic gesticulations of Caliban in this play.
