When you work for years at something, 16 hours a day, you either love it and want to cherish it - or you close the door and move on. Honestly, I can't blame any actor for not wanting to be glued to their Trek character for a lifetime. As fans, we expect so much from these people. But it's wonderful to see the ones who have an enthusiasm and passion for their role, their show, the message, the franchise, etc. Without getting into a bitter discussion about actors who are not fans, who are some of the Trek actors that convey a genuine love of Trek and never seem to tire of being called Captain, Commander, Ensign, etc.?
