Good, but audio difficulties and plot holes bog it down

Rating: 6/10 (20 December 2014)

If it weren't for audio troubles and a few confusing plot holes I'd give this movie an 8 or 9. There are several moments of conversations where lines are muddled or overpowered by background noises, leaving you unsure as to what is being said. The story itself is interesting in terms of main plot and visuals, but my family and I left the theatre confused with many aspects of what went on and felt that there were plot holes that made the end result questionable.
Actually, even the beginning of the story is questionable. At this point, I am still confused with the central feature of the plot, being that the Earth's agriculture is dying. At first I thought it was due to muddled speech, but I've asked on message boards what was said, and everyone that has replied said that it was 'left open to interpretation'. To be honest, that just seems like lazy writing. I appreciate that the space travel features were guided by a theoretical physicist (albeit the science probably went over most audiences' heads); but certainly someone in agriculture could have guided them with a reasonable explanation for the Earth situation to make it seem realistic?
Look, over all it's a decent movie. It could have been great, but if people leave a movie theatre not understanding what was being spoken or are annoyed with questioning plot holes, then it's hard to judge something as worthy of greatness.
