I like the concept of the show and generally liked the results they came up with, though I, too, was kind of disappointed that Abra decided to go with the 'burned out' alien planet.
When they said 'forbidding landscape' and said they wanted something completely new and original, the first thing that popped into my head was "How cool would it be to do a crystalline landscape?" I'm thinking bright jewel tones, glittering sand, no plants whatsoever and no indication of animals... beautiful but definitely not someplace you'd want to have to try to survive.
