The greenhouse scene was decent. The extended plaza scene was good but it was rightfully cut because it raised more questions than it answered. I also thought the flashback was decent. Everything else was superfluous. The Advent on the other hand, is amazing. It gives us more info about David's creation and what happened to Shaw, more info about the Engineers' "way". It delivers on things we didn't get (enough of) in the movie. Wish they had found a way to put these things into the movie itself instead of having it as a viral (unreleased) video.
