While I'm pretty let down by the visual treatment, I think this is some of the strongest writing and execution in the jam! The "under the surface" theme is echoed in several areas of the module, and it functions really effectively as both a narrative adventure and a primer for a full-ass shore leave destination.
You can piece together the truth in a variety of ways and there's something interesting around every corner. You've a good few sessions of sandbox play packed into this one and that's a hard bargain to beat. Cirrus Station could be plugged into any campaign and it would be well worth the detour!
