Back to the original thought: you are correct. The movie moves nicely along, but is badly in need of a plot. And more coherence.
AND i for one would like to see if the 23rd century could invent the TRIPOD, related to the TRICORDER, which is used to hold a camera STRAIGHT AND STEADY. I really can't understand why they would pay $mm for effects and then make them almost unrecognizable by shaking the non-existant camera.
