I've seen Defying Gravity. Too much "Grey's Anatomy in space" for me, and the sci-fi was shoddy at best.
I remember being annoyed that they were given a chemical to stop their sexual desires, which they later stopped using because it was claimed to be the cause of their hallucinations, but once that was proven to be a lie - they simply forgot to use it again! Would've spared them and me a lot of unnecessary drama.
