I agree that Amy should've been given a little more of the limelight. I think she got especially jipped during "Farnsworth Parabox"; the other characters got a good look into the lives of their parallel selves, and Amy just painted nails for a few seconds and that was it.
And as much as I love Zoidberg, I think he's at his funniest when he interjects, rather than when he's the center of attention. "Taste of Freedom" has to be one of my least favorite episodes along with "That's Lobstertainment"..."Crustacean in Love" was okay...but in general, Zoidberg just isn't as funny when he's the focus. It's much funnier to see him 'whooping' in the background, and being emotionally abused by his co-workers
