PROBLEM: Review: Hard to find a better direct-wire wall timer of this quality. HOWEVER, this is the third one I have purchased so be warned that they will eventual ware out. The timer will eventual stop counting down and get stuck, leaving your device always on. I have mine hooked to turn off a wall heater in the bathroom. It works well for that. NOTE: Even though it will eventual ware out, they usually last a few years before they do. So yes, they are worth the price. BE WARNED: If the start waring out replace immediately as they will get stuck in the ON position... Thus, 4 stars. 
 Polarity: Negative

SOLUTION: False

PROBLEM: Review: Bill Nichols is full of words and empty of thought. You need a machete to slash through the tangled sentences in this book, and what you'll find beneath are simplistic, flawed ideas that aren't developed but buried under more verbiage. Nichols stitches suffixes and prefixes to ordinary nouns, creating monsters like "situatedness," "hyperrationality," "reconceptualization," "polyvocality," "relationality," "talismanic"(!), and the pseudo-literate's favorite word of all: "juxtaposition." Each of those words costs as much time to understand as a whole chapter of Erik Barnouw's book (which is succinct, informative and even humorous). Mr. Nichols should be sealed in a cave and his books slung into outer space, for they pollute the body of film knowledge. Don't buy "Representing Reality" unless you want to know how confused Mr. Nichols's reality is.
