Trapped by a wicked witch in the woods, two siblings survived after been obsessed by a great consternation. Now they turn bounty hunters tracking down witches all over the world, but their worst nightmare lies within; it is the fabled Blood Moon.
There isn't much to this beyond the poorly staged, rapidly edited violence; the witches, all but devoid of backstory, are basically canvasses for cartoon splatter.
The whole kidding trope, which you can bet was ordered by McKay and Ferrell, is pretty lame, and defeats the leads' attempts to bring shadings to cardboard cartoon characters.
Very lean and speedy... Its primary goal seems to be to entertain as quickly as possible and get the audience back out the door before the story gets old.
If this long-delayed and blatantly pandering CGI malarkey is anything to go by, Hollywood's current craze for fairy tales isn't going to have a happy ending.
