I've just finished watching it yesterday, and I liked it from the start.
I rate it 8/10
besides the awesome CG they used, everyting in the series is detailed, even the backgrounds used are full of color, unlike some anime series I would know.
The plot is just awesome. No plotholes and hax characters, plus there is a humanistic side into it.
From the ship names to the places, Last Exile is full of fresh new ideas and is devoid of any doppleganging.
What are your opinions on this anime?
