This started well but descended into cliché and soap opera. A half-decent science fantasy idea was ruined by marital bickering, teen opera angst and the usual Wesley Crusher type.

The worst aspects are the serious goofs that no-one seems to have noticed. Chips of titanium refined into spacecraft parts in a few hours. A very sophisticated robot that can't string a decent, meaningful sentence together. (I know: its cryptic comments are merely a plot device but they could have contrived a decent reason for its inarticulacy.) Most annoying of all were the repeated references and scenes "on Alpha Centauri", shown as an Earth-like environment. Alpha Centauri is a star. The planets that orbit that star would be numbered - Alpha Centauri 1, 2, 3 etc.
