At this point if there isn't a large scale battle with all of the GL Corps vs the Parallel Parking monster and the Corps simultaneously shooting all their rings at said monster, then this movie will be a big fail for me.
Hell, as already seen in the trailer, they shot off their damn weapons all at the same time into the air just because they were celebrating their strength in numbers

so they better at least do it when facing a world eating monster known as Galactus....errrr....I mean the Parallel Parking dude.
