Defying Gravity is a sexy, provocative thriller set in the very near future against the backdrop of our solar system, in which the eight astronauts from five countries undertake a mysterious six-year international space mission on the spaceship Antares. They can't run from karma, however, as their past actions reveal intimate and interconnected relationships that have a strange effect on the present. As the astronauts travel towards Venus, we travel into their past with flashbacks to earlier years from the grueling selection and training process. What could have happened? Maybe there is something to this fate thing after all.
Some say the show is a little bit like "Grey's Anatomy" in space, others its like "Lost" in space. Well I personally think it isn't anything of this.
If you watch this tv show you get a tv show which is very realistic. No real fancy technical stuff what we all might like about Star Trek, no fighting scenes like in Star Wars. I don't want to spoil anything, but the plot is simple: make a journey through our solar system which really takes a long time and a mystery factor which everything makes more interesting and a starship which isn't that big.
You also get some realationships between the actors.
But there is action in this TV Show. I never get bored watching this and I am a little bit sad that the show got canceled after the first season. There is no big ending, but at least the show got a good last episode with not that big cliffhanger (like in Alcatraz).
I suggest give it a try, watch the pilot and the 2nd episode. If you do not like it after that, don't watch the show. If you do, watch it. It is not a waste of time.
