yeah just makes me wonder two things: 1)why aren't the others that good? 2)will that henshin change once usagi figures out she's the real princess?

I thought it was too long, but very different and more creative than the rest . I dont think it will stay like that, it will probably be speed up to match the length of the other transformations.

I hope when Moon gets her second "upgrade" (like in the anime R season) they'll have something better. Likewise for the others (Mars, Mercury, Jupiter). Only time will tell.
