S03:<br /> They should have ended with second season. Actually it had already satisfying end, but series popularity means money, and creators can't pass on that.<br /> Third season starts making mistakes, by repeating a lot of things from first two ones, in addition adding unnecessary and most of the times illogical events and even things what goes against already established story details, also adding very cheesy subplots and really unnecessary social justice political views what starts destroying what they managed to create in first two seasons.
