I completely understand where bluedana is coming from, and I do recognize that they were in particular going for a kind of charming naivete with the human characters in ENT, including Archer. For my money, they quite missed that mark and mostly wound up with petulance instead, but of course mileage will vary.
(I also agree that ENT need not have replicated the swaggering smugness of the other televised Enterprises. I do think there are ways to depart from that and still have the heroes look competent, though -- a different thing than being without flaws -- which I don't think was achieved consistently with Archer. In fact we have models for such protagonists in the historical pioneering astronauts to whom Archer is meant to be an heir.)
