Doesn't look good "out of box", so what am I doing wrong ... ?

I've got to be missing something obvious,but am not finding anything in the docs that I'm able to find, so will ask ...

I'm running Drupal 7.2 with 7.x-1.8 of Superfish installed ... as can be see in the attached, I've got the Pomegranite(sp?) style enabled, but, as can also be seen, the sub menus are getting gradually bigger, and are offset from the previous menu ...

I've tried to tweak various settings within the 'block -> configure' section, including changing from / to the default style, the color seems to change, but the submenus continue to 'look terrible' ...

So, I guess the first question is, out of the box, should I have to tweak the CSS files in any way to get the menu to look *at the least* as together as the examples show on:

I've made sure to remove DHTML and Lucid Menus, which I was playing with prior to Superfish, fearing that there might have been some sort of conflict ...

Looking at the source (Browser -> Show Source), the menu references classes that I can't find in any CSS file (ie. sf-depth), so figure that there are defaults being generated somewhere, but, again, I would hope that the defaults would somehow *look* good as a starting point ...

Any pointers / help on this would be appreciated ... I'm figuring it has to be something fairly obvious that I just don't understand about Drupal yet ...

Thx ...
