Oh dear lord, why is Saga that good? Thank you Brian Vaughan. 
 To give you the big picture, there's this great war between the inhabitants of a planet and its moon. It's a galaxy-wide struggle. In this war are two star-crossed couples Alana and Marko, each of them belong to the warring races. They want to hide and escape. That's the premise, so far. It's multithematic, with elements of love, action, scandal, a bit of horror - all inside the sphere of an epic space drama. 
 Obviously, Saga will be a multi-generation story (100 Years of Solitude of graphic novels?). That's good because that only means that fresh Saga issues will grace comic stands for a long, long while. Oh yeah.
