Six Flags Discovery Kingdom Review - Is it REALLY that bad?

In this review, I talk about Six Flags Discovery Kingdom in Vallejo California. This park is home to some interesting roller coasters such as Joker, Medusa, and Kong, and is a part of the Six Flags chain of parks. There are some things that I like about this place, as well as some things I don't like, but does it really deserve the hate it gets among coaster enthusiasts?
