What struck me about this episode was that the Aurora Box ended up on top of the Tokyo Metropolitan Government Building, which is a major landmark often representing Tokyo in movies and TV. So it's amusing to see it featured so prominently in a Power Rangers
episode that's supposedly set in some American city (I forget what generic-sounding name they're using this year).
The interesting thing about the "Bigs" character design is that it worked as well -- or even better, really -- upside down as it did right side up. He looked far more menacing when dangling inverted inside the Aurora Box.
The five Ultrazords merging to form a star-shaped "face" is an interesting bit of design. The new Megazord is one of the least stupid-looking ones they've had in recent years; I almost like it.
