It has nothing to do with being "cinematic".
The trailer paints the game as a frenetic action shooter and that's plainly not true. A more paused trailer, also highlighting exploration and trading, would be more truthful to ED, but I guess that wouldn't sell the game so well.
It has *everything* to do with cinematic... because that is what the trailer is. A cinematic trailer.
Take Blizzards trailers... they have absolutely NOTHING to do with the gameplay. Yet I don't see people moaning about them.
