Too much Matt, the messages and the story are somehow disconnected

Rating: 8/10 (1 November 2015)

The theme, costume, actor and actress are all great, 10/10. but I think the message about respecting nature, hope and fight for survival are somehow not align with how the story goes.
How Matt work on communication feel way too easy and smooth, and what is so important about Jessica's disco much? the character doesn't even show up more than 5 minutes, and that is a huge waste of Jessica being in this movie. and others like Chiwetel, are too having too little time, which makes all other characters feel bland. Viewers would be wondering why those 5 people are willing to risk their life trying to save that one guy. And two useless love relation, Jessica's and Kate Mara's. That kiss doesn't have anything to do with the story, etc.
if there is a director's cut like 4 hours length, could be much better.
