Visible crew/equipment: In the scene in the cavern where Wesley fires his phaser to heat the rocks to keep him and Picard warm, Wesley's shadow is in the wrong place. The camera is in almost a direct line of sight between where the rocks are (which are supposed to be providing the light source) and Wesley with the cavern wall behind him. After Wesley fires his phaser and the room illuminates, his shadow should be either directly behind him or to the left of him, but his shadow appears to the right side of him. The only way his shadow would be there was if the light source was off camera a good distance to the left.
Plot hole: Why would the miners send a shuttle to get Captain Picard when the Enterprise has a compliment of shuttlecraft on board? Also, how could the Enterprise engineering team (led by Lt. Commander LaForge) miss that the thruster quad on the shuttle was near failure?
