Louis is the best character, Donna is the worst. She wants to be one of the leaders of the firm, but any suggestion that she has anything to offer the firm professionally is laughable. Shes great if you want to know what to get someone for their birthday but anything past that is out of her league, and she knows it but still manages to con her way up there. I really wasn't rooting for her and Harvey but the outcome makes the whole show a 4/5 imo.
