A bit of trivia I discovered recently, but evidently the corvette the resistance uses is the Tantive IV. The very same one from A New Hope.
If this isn't a statement of the movie's character, I don't know what is. We didn't need the Tantive IV to come back, and I'd rather have a new corvette to add to the list of named ones so we can develop its new history. It was completely unnecessary to make it the same ship except for fan pandering. Same with Luke's X-Wing. Same with Palpatine. *angry sigh*
So now that superlasers can be mounted to Star Destroyers, A. I guess the death stars are obsolete then and B. When can we get our special title card to mount superweapons to ISDs?
Also I wonder which is the stupider idea: Superlasers mounted on ordinary ISD-Is, or the Sun Crusher?
