I only started watching it last year and I look foward to its return, its filmed pretty well, saturated colors and great scenery.
I never paid much attention to this show when it first aired, found the presentation way too clean and soap opera like...still is in many cases... too many model-like people on one island.
Maybe if I didn't get a HDTV last year I would not be watching, seeing that there is so little HD material on worth watching.
Still not too sure what the plot is, since I never saw the previous seasons, but hell, its good eye candy.
