Not everyone is bound to give this week's DVD release of the vampire romance Twilight a second thought. But if you, like us, tore through Stephenie Meyer's Twilight novels (that would be Twilight, New Moon, Eclipse, Breaking Dawn, and the unfinished Midnight Sun) within the span of a few days, barely stopping to eat, breathe, or sleep, inexplicably unable to pay attention at work or school thanks to an endless swarm of thoughts of Bella Swan and her vampire beloved --- dare we say his name? --- Edward Cullen...well, then you're going to need a little help deciding which of the various upcoming Twilight DVD and Blu-ray options you should pick up this Saturday (March 21). And did we mention the enormously enticing box sets that Summit has created for your viewing pleasure? Twilight -- it's like our own personal brand of heroin, only much, much more addictive.
