I know it's something supposedly minor but am I the only one who is very disappointed at how bland the new Imperial, ahem, First Order vehicles look like?

The TIE/fo in particular (it's been practically confirmed that's the official name based on the X-Wing board game and Bandai's upcoming scale model), it's just a normal TIE-Fighter with some very minor detail alteration and negative colour scheme! White radiator/solar panels and black hull! ... Meh.

Some aircraft & spacecraft designs don't change very much over time. And the TIE is probably hard to improve on.

In the real world, B-52's are still flying, and Russia's still launching Soyuz space capsules.
