That's why I said A mirror and not THE mirror ; )
As to the overall design... well I mostly like the nacelles. The rest I could happily dump along with the alien ships from Battleship, nu-Transformers, and every other sloppily over-detailed, garish, cheap-looking piece of photoshop design that has emerged from Hollywood sci-fi in the past 10 years. (luckily it won't impede my enjoyment of what sounds like another fun popcorn flick).
This is correct.
