From Jennifer Thomas of the Pioneer Local (Illinois):

• Review: ABC’s ‘Defying Gravity’ launches soap in space
  “The first two episodes of ABC’s upcoming show, “Defying Gravity,” were both better than I expected but not as good as they could be. Sold as sort of a “Grey’s Anatomy” in space, it has potential, but it also has an usual mixture of sci-fi and soap. Mainly, I could do without the pop-rock montages and the philosophical voiceovers from lead character Maddux Donner (the always likable Ron Livingston). Those kind of voiceovers work when done by Meredith Grey, but they don’t work as well here. “Defying Gravity,” though, is very likable — especially when leads Laura Harris or Livingston are on camera.” Read more.

From Randy Shore of the Vancouver Sun:

• Genre-twisting space adventure, Defying Gravity, blasts off
  “Defying Gravity boldly goes where no relationship drama has gone before. When flight engineer Maddux Donner is suddenly added to a deep-space mission departing for a tour of the solar system with an eight-member crew, including his current lover and a former girlfriend with a torch for him, things are going to be awkward.” Read more.
• Interview: Defying Gravity is science FACTion
  “If human beings want to visit the other planets in the solar system, what would the ship look like? What technologies would be required? Executive producers Jim Parriott and Michael Edelstein asked these questions of themselves and NASA to create the environment for the space travel drama Defying Gravity.” Read more.
