Trailer ruined expectations

The full length trailer is was ruined the movie. Seriously. The teaser was great, and if that had been it, the response from the fan community would have been much more positive. Like many people have mentioned, if you've seen the trailer, you've seen and understood 90% of the plot. Not 90% of the movie, but the plot. We should have never seen cuddles! We should have never seen inside the urn! We should have never seen the giant head! Leaving aside the fact that the original space jockey's ARM was the size of a human, the Juggernaut simply looks like an entirely different ship. No bone-ship. Different control room. So forth. If Scott and company are able to explain why the bone ship looks so incredibly different than the Juggernaut, then awesome.. I hope the sequels will eventually bring us to understand why the boneship looks so different as well as the eggs, so forth. I look forward to Shaw & David's escapades. They could make a good team, especially if David is able to get in a suit or something. He needs a new body...
