Interstellar

Last week I went to the cinema, I watched the film "Interstellar".
I didn't have any idea about the plot of the movie, but I had watched some of Christoffer Nolan's films before and I loved them, so I thought it'd/this would be a good one too.
If you haven't seen the film yet but you're thinking about it, please stop reading here.
At the start of the film, a new world is shown. In the new Earth planet, the sun is getting blocked by ashes.
The main character, played by Matthew Mcconaughey, is a father of 2 children whose mother died years ago.
He used to be a worker in the NASA, but when the world started to change, he had to resign of his job and become a farmer in order to be able to feeding his children.
One fine day, his daughter starts to receive some weird signals from the space, like coordinates.
She and her dad decide to following the signs and they arrive at a hidden place, property of the NASA.
The people in that place say to tell the father that they've been waiting for him, because he's the (only) one who is able to carry on a mission for/with the purpose of saving the world.
At the beginning, he don't doesn't want to leave their his children and go to the space, but when he realises that it's the only way of saving the Earth planet, he changes his mind and goes to the space.
The end of the film is very unexpected and it made me feel curious about space and stars.
Even though the film takes a long time to be watched (3 hours), I highly recommend it if you feel interested about in the plot.
