Pre-release materials are the worst, and often contain awful spoilers.  I intentionally avoided them for Star Wars.  During the previews when I saw Star Wars, one of the people I went with did his best to ignore the Captain America trailer, because he didn&#x27;t want it spoiled at all.  You watch enough ads&#x2F;pre-release materials to decide you want to see it, then once you decide to see it, you ignore everything you can.
