Could've been a hard sci-fi master piece but missing hard sci-fi details

Rating: 5/10 (24 November 2016)

This movie was neither dramatic enough for pop-corn viewers nor hard sci-fi enough for serious thinkers. the experts just went there and start talking English? come on, the pop corn movie "independence day" even showed helicopter flashing big light patterns at the alien ship as a reasonable starting approach. I expected to see different ways of communication attempts for alien languages; 1. light spectrum. 2. sound frequency 3. heat signal 4. electro magnetic waves 5. magnetic field. 6. gravity waves To be able to see through time dimension at least associate this back story with some quantum theory. I can write a sentence with flower patterns in circles but that's not enough to give me the future seeing power. It is just not convincing.
