Do not waste your time. If you really want to know what happens watch the trailer and just make a guess. Odds are that you spent almost as much time/energy with that compared to what they put into the overall plot.
This thing was created by the business side of the movie business and it shows. They took a whole bunch of ideas and shoved it into an extended trailer that cost them $100 million and they got $971 million. So, I guess Illumination executives have no problem destroying future revenue as they cash out and move to the next IP.
