Really boring

Rating: 3/10 (6 November 2013)

Well.. i've been spending around 3 weeks searching movies here and only getting movies having at least 5 stars of rating. but with this movie i've been completely disappointed.
Why does this rating 7,1 ? the movie starts very interesting, it makes you thinking about a great sci-fi movie with a complex story but after 70, 80 min you start getting really bored. too many histories happening at the same time and they don't explain anything about the major history.
Why do the aliens come to Earth? How did it happen? Why do they live underground? Why do they eat people and not another things?
these are some questions.
they throw the characters into the movie and simply don't explain nothing about them.
from now on i'm going to be careful with the ratings cause i haven't read any review before and i watched a stupid movie. i think if i had read the reviews i wouldn't have chosen this horrible movie.
