Structure: Every episode shows us glimpses of the future, specifically the events we will see in season's finale. We get to see more and more of what's about to come and those little scenes always provide shocking twists and plot revelations.
Verdict: Season 1 and 2 are truly amazing, season 3 is very good and after the producers were forced to change the channel the series airs, season 4 changed the show a bit - there is more mature content in it, but it doesn't feel like the same series anymore. Nonetheless, it's still worth watching.
What makes it so great? Fantastic performance by Glenn Close and incredible plot twists in meticulously planned stories. The opening sequence is pretty impressive as well.
