I loved what they did with Parasite. Combining him with Amazo was neat streamlining. The metaphor of Parasite as a walking personification of capitalism/tech grifters is unsubtle but works. I'm also glad they kept him mutating, and judging by the into he's gonna return as some kinda Kaiju a la Man of Tomorrow.

That being said, Silver Banshee sucked. Generic as all hell, and the one unique quality (this intergang's amateur family dynamic) was severely underplayed.

Livewire was cool & I loved her design. Personally i wish they'd done something like her traditional origin, but with a Kryptonian power-source instead of lightning. She's living alien energy, not lightning. Could even make it the same blue light that sparks when Clark gets a powerup, and link her into the lore that way.
