Takei is a pleasant enough guy who has gone the Shatner route by whoring himself out to anyone who will take him, as long as it is work (or, perhaps uncharitably, as long as it means TV exposure). Shatner did it in the 70s and 80s, before the resurgence of his persona in the popular conscience. Takei is too old for it to really take a foothold, but more power to him for staying out there swinging.
