Harley Quinn Showcased in 'Suicide Squad' Trailer

Boy, someone wants to rip off Guardians of the Galaxy, don't they? In the trailer at least. This one takes a totally different tone than the first, super serious teaser did, and it doesn't look half as bad as Batman v Superman- although what could? Not sure though. I think more than half the effect is "Bohemian Rhapsody" playing throughout it. And they're not teasing Batman, who is supposed to show up in this movie, as played by Ben Affleck.
