Windows 7 is ugly. So is XP's Luna theme, and Vista's weird transitional look. But XP and Vista at least let you go back to the classic Windows 95 look.
How to make Windows 7 pretty: switch off transparency effects.
I also like the classic Windows 95 look but dont you ever get bored to it? I had been using XP 6 years but finally in this month my work laptop was upgraded to Windows 7. It is quite refreshing to have a new look and it is not that bad. Maybe not the prettiest, drop shadows look odd.
