I think the story was too formulaic last time too.
Charismatic, irresponsible protagonist with a girl he's loved since he was a kid, who love him but they can't be together b/c he's immature. He gets a power ring. Doesn't want the responsibility. Misunderstood scientist falls backwards into powers and madness. He causes havok. Our hero grows up, overcomes great fear, defeats the villain, saves the day, gets the girl. Roll credits. WAIT! easter egg scene setting up for the next film. The end.
Green Lantern is an outside of the ordinary hero. He needs to have a story that reflects that.
