Probably the show's greatest strength is its imagination. The various alien planets that the crew visits are filled with bizarre flora and fauna, and present the most interesting challenges that they face. Concerning their other challenges, the English title is a bit misleading. The crew are transported far from home, but they're never lost; they chart a course back very quickly, and the difficulties come along the way. While they face potentially life-threatening dangers, there is never quite the sense of them barely surviving by the skin of their teeth. They encounter numerous planets with breathable air and edible food, and the whole struggle for survival against the elements feels tamer than it could have been.
Where the show falters somewhat is in a lack of focus. The story has three main twists, each leading it in different directions, and I think that was one too many for a 12 episode show. Fortunately it breaks the typical short anime curse by being a complete story, but it has to grind through a lot of exposition to get there. The final two episodes particularly suffer in this regard, with 11 being almost 100% exposition about one twist, and the first half of the double-length finale being exposition about another twist. Consequently, the climax feels very dry and devoid of action compared to earlier episodes, with back-story flashbacks taking the reins.
This one hovers between a 7 and an 8 for me, but I'll nudge it to the higher score for its imagination and the rare trait of having an actual ending.
