Perhaps my post was badly written so when I wrote "ordinary guys",I should have put the emphasis less on ordinary and more on guys.
After all,TNGs pilot and premiere season did focus on Rikers perspectives (as did Voyagers pilot on Paris).These (yeah,male,square-jawed types)were probably percieved by the producers as the most accessible to the (mostly male) audience.
Maybe I'm in the minority,and showing my prejudices,but like I said before there is no one on the Enterprise command crew that I can empathise/identify with.
