I finished watching Suits in a week and I thoroughly enjoyed every bit of it.Each series is very interesting and entertaining.
I love Donna most of all and the love, trust and understanding between Harvey Specter and Mike Ross and I wish it didn't end without any further solved cases between Mike Ross and Harvey in Seattle.
Each character played their role very well and it's hard to say who was the most amazing of all.Hats off to Louis Litt although one would tend to think how stupid he is but he played his role excellently well.
You also get to learn a lot from suits cos they built a culture of togetherness which helped them to work together, they never gave up, supported each other, forgave each other and these character traits that they nurtured at the firm, helped them to consider each other as family.Not just that , they were the best firms cos of the principles they followed.
