I actually quite like this design and always have. It manages to look interesting and somewhat utilitarian at the same time. It's certainly not just a simple box. It's also interesting that what we see here is pretty much the full-size mock-up with but only a few tweaks: the underside detail of the miniature is added, a little lifting of the nose, the roof isn't quite as flat and is a bit more curved (for more interior space), the stabilizer/rim at midsection is tidied up and the front of the hull bottom is matched to the curvature of the leading edge of the bow.
Amazing they built such a complex full-size prop on a television budget.
