Cruel and beautiful, Whiplash stands for the search for excellence, the extreme way – pushing people into the abyss hoping they will emerge from it as a once in a lifetime genius. Because real (musical) talents, those who aspire to be one of the greatest, will never be discouraged.  By nothing. Not even Terrence Fletcher, the despicable musical drill instructor of this movie. Moreover, in the end, you might even need to fight your master to reach the Olympus; the movie meets this expectation with a grande finale, wherein everything comes together.
Fine movie and a strong reminder that drums really are a powerful instrument.
