It certainly has excellent play features. There are 5 reviews on brickset and 4 of those give it 5/5. It also appears on 2 "best ever" bricklists and zero "worst ever", so I think we can agree that owners like it. It has 3 vehicles and 3 astronauts in under 300 bricks. I should mention its role as Archie the Library in KDog's Lego Space comic, which rocks. By the way, the alternate builds are great too, as I remember. It's not so expensive, I thoroughly recommend the sceptics to pick up a copy. As for its unconventional looks, the colour consistency is good, only the small feet and big hands let it down in my view. It would look a lot better without the jet feet, maybe put some big hoverdiscs there and it would look a lot better.
Loved it loved it loved it.
Seriously, I respect different views but try it before you slam it. This really is a great set.
