@LukeAlmighty Well, what do you mean exactly? I really like foreshadowing, where I as the viewer simply don't understand the references until they happened - example that comes to mind is OP2 of Jojo's Bizarre Adventure.
What I did dislike is the second version of Tengen Toppa Gurren Lagann where certain things, like a new crew member that you otherwise wouldn't have know about, were clearly shown as such.
