The best character in terms of charisma, leadership, and goodness of heart was Patrick Stewart’s portrayal of Captain Picard. In the realm of Star Trek, he knew inside and out Gene Roddenberry’s dream of what Star Trek could do, would do, even when he passed away. Captain Picard carried that vision forward in a way no other character of New Age science fiction has ever been able to do.
In terms of charisma, Captain Picard knew how to make people like him. The officers underneath his high status—albeit not Admiral or even higher like with Captain Jim Kirk (William Shatner)—always followed his steady example, or tried to. And no one ever tried to question his character because there was no reason to, except in “Star Trek : First Contact.” His charisma even carried sway with aliens from previously unknown worlds, because he always respected them even when it was difficult.
In terms of leadership, Captain Picard knew how to inspire people to obey and follow his command, whenever it was necessary. As a leader, he told his officers to do their jobs and they did, because he knew how to compliment them for a job-well-done, and whenever they made mistakes, he brought them up subtlety. Even when he was compromised as a Borg, (because his loyal crew knew him and loved him), they understood they had a duty to him as his bereft acting-officers in command.
In terms of goodness of heart, Captain Picard knew how to do the right thing whenever it was demanded even if it was unpopular. Too many examples exist in episodes I watched in which he helped alien species despite the prime directive. In the prime directive, one is not supposed to alter the future of any alien species by providing technology. Although occasionally he would aid Romulans with the above mentioned when they called for aid (S.O.S.), he would still abide by his principles but never at the cost of Goodness. Captain Kirk, Janeway, and Benjamin Sisko were never so pure.
Even though Star Trek succeeded in breaking many social barriers in cinema, it couldn’t have been done without the help of Patrick Stewart. Captain Picard embodied the proper principles of charisma, leadership, and being good in general. Too bad Patrick Stewart doesn’t portray Captain Picard, since his crew is retired and “Star Trek : The Next Generation” is over.
