I never got into Miami 7, but I was a huge fan of Sabrina on Nick! Generally I loved Nick shows.
And then on Disney I watched stuff like Smart Guy and Boy Meets World, but nowadays on Disney everyone seems to overact (not that I watch them anymore....blame my little brother.

)
High School Musical is ok though, I just thought I'd watch bits seeing as I was bored on the plane, but it actually ended up being good (predictable but still good)..
