Fair enough. They really do. This one's actually pretty restrained, by third trailer standards, though.
Yeah, it's all a matter of retaining a fresh perspective going in. It's of course much more difficult to do these days with all the spoilerific headlines, but it can be done, and the experience is more rewarding. I only know the very basics of this movie, ie the setting and the relations between characters and I feel that's all I really need to know.
