Season 1 was the best for me, second was slightly worse but third was the worst. However the fourth one really kicked ass, John Lithgow was by far the best of the main villains on the show (not taking anything away from S1). Ever since I saw Blow Out for the first time - and that was like 15 years ago - Lithgow was on my shortlist for a perfect villain.
From the other characters I like (or liked in case of their death) Batista, Doakes, Masuka, Quinn and Rita. LaGuerta annoys me from time to time the same as Debra. I never liked Lila or Miguel that's the main reason I rate seasons 2 & 3 lower then the other two.
