I don't think I ever watched another Brazilian show before so to me this was a first and I can't say I'm disappointed about the quality of 3%. It has a good interesting plot, with enough twists and turns to keep you interested. I watched the first two seasons in less than a week and never got bored. Once you're in the story you want to know what's going to happen, and that's a good sign. I wouldn't say the acting is Oscar winning performances but it's certainly not bad at all. Each character brings something to the story, and that if you like him/her or not. For a sci-fi it has interesting gadgets, but don't expect high budget special effects. It's simple, low cost but effective. I'm looking forward to the third season of this Portuguese spoken series.
