Don't get me wrong, the whole series is really good. Actors, stories, special effects... it's all great!

But the relations between characters, especially those of the Robinson family, lack originality at a point that it is unbearable. I skip them all the time, cause they are long, basic, useless and boring.

Also, there is a character that is extremely annoying, always doing the wrong thing, saying stupid things... I just want to punch her in the face every time she's on screen. So I skip her too.

Other than that, it's something a family can watch. It may be an entry door for children into sci-fi.

But, for an adult, who's been into great sci-fi shows, this series can be frustrating, and sometime even, infuriating. It could have been such a hit, with better dialogs...
