Sorry to paraphrase Bon Jovi, but really.
MTV (remember when they actually played music videos?) apparently thinks a reality show about morons hanging out in clubs "down the shore" is entertaining. As a result, we have "Jersey Shore," a show (actually, more like a giant cliche) about "guidos" and "guidettes."
The people in this show are not attractive, not smart and not entertaining. This is probably the worst piece of crap ever to hit the airwaves (errr...cable). And the fact that's they're Italian-American makes it even worse. This show does nothing but reinforce the stereotypes.
Give it a look, if you can stand it.
