Some parts of the CA park I thought were awesome, but the Bugs Life area was a lot like the Dino area in AK rdeacon mentioned, and could have been so cool with just a little more thought and work (like if the caterpillar train had circled around the area instead of just a small space, etc).
I agree with rdeacon about the stuff Walt hated... and don't get me started on the whole carnival "theming" at CA is actually anti-themed and...

A copycat of Knotts was not what the world needed.
They should have done the "America" park with the Calif. stuff just a part of the entire park.
