Season 1 was pretty awesome. The story, the plot, the characters are carefully planned. Each case in each episode is something different and makes us think. The twists and turns are enough to make you get up from your seat. However, I wish they cut off the flashback part which is shown very frequently.
Season 2 is not that good and very less interesting compared to first part. They have raised the bar so high that they have to keep up now.
