The Media Sub Type "TV Show" should be set on import. By either Carnac or by the Tag on import option. I have several views. This is the most frequently used:
View Name/Function | Items to Show | Sorting | Files to Show Rules
Series | Series, Season | Season, Episode | Media Sub Type = TV Show
Not Watched | Series, Season | Season, Episode | Media Sub Type = TV Show, Not Number Plays > 0
Genre | Genre, Series | Season, Episode | Media Sub Type = TV Show
Recently Added | Nothing | Import Date | Media Sub Type = TV Show, Imported last 1 Week
View name is the name you will see on the secondary roller. The Items to Show it the levels in the view. Sorting is how the media is sorted. Starting with the first item, and then sorts on the second item if there is more than one match on the first, and so on. Files to show is the place where you decide what to include in your views, and how it's supposed to look when you browse it.
You're right that this is not super intuitive, but it IS very, very powerful once you know how to do it. You can make what ever type of view you want. There's not really much else to do then to try it your self and make a few views to get used to how it works.
