When the rail expands to cover Scottsdale as well as another East West Route (Indian School or Camelback?) I will add a star. Being from New York and taking the subway to work every day, I never thought I would even want to see another train again much less ride it.
However, given that the traffic here is brutal, I have embraced the light rail in it's limited role. Since I live in the East Valley and need my car for work I can't use it. Me and friends do take it for ball games and shows that are downtown and it's great that way. I also use it if I have a series of downtown appointments and working at Central and Thomas makes that happen. Plus it's cheap!
My only concern is that they really didn't take security to seriously. It's too easy to ride without paying since there's not enough money to go around to provide for police to check tickets.
