It was crap. Not shit, but just crap. Excellent art, amazing character designs, but shit story. Half of their destinations were just random phrases. "Summer of Love" ended up meaning THE FUCKING END OF THE WORLD, Earth was hidden inside the planet, and the union of Eureka and Renton ended up causing the Nirvage to transform and save the world.
If the story wasn't something a drug addict made, then it might have been good.
