Personally, I think Interstellar truly delivers as Christopher Nolan's best masterpiece. Maybe the general population would put this blockbuster seventh place in the category of the 10 best space movies. I for one would rank it third behind First Man starring Ryan Gosling and Alfonso Cuaron's Gravity respectively.
I like Interstellar, because it focuses mainly on personal loss and the love one feels for their family. The beginning is spectacular! I love how it opens with a farm surrounded by crops of corn, a humble beginning. Its much better than starting the movie with all that intense, apocalyptic action we see at the beginning and end of superhero movies.
The story plot structure is great as well. Cooper is going into space with a crew to a mission to find a new habitat for the next generation of mankind after the food resource begins to die. But even more so bittersweet, he must say goodbye to his beloved daughter Murph and the rest of his family. As he descends further off into space, time becomes either slower or quicker, and his family starts to age, even though, he's been in space for a brief period of time.
Along the way, Cooper makes a lot of good, trusted devoted friends on his mission, including those two hilarious cubicle robots, CASE and TARS (I often confuse one for the other). Its neat when they descend into the black hole and kiss goodbye to their galaxy, because it reminds me of the star gate tunnel in Stanley Kubrick's 2001: A Space Odyssey and the robots make me think of the monoliths because of their shape. I love the suspense that builds as they land on different planetary terrains.
Above all, I like it when Cooper descends into Gargantua's abyss toward the end and finds himself all alone in that 5th dimension, which appears at first as a library of flashbacks. Don't wish to spoil for you guys out there, so best not to read my review. For those of you that have watched Interstellar, I'd like to say how Cooper at first feels depressed and personal emptiness for saying goodbye to his daughter, and the loss is greatly heavy I agree, but soon realizes that the theories she had of a ghost in her bedroom was his presence all along.
He then is transcended to a new dimension and awakens to find his daughter Murph as an old lady on her deathbed just like the Professor Brand, surrounded by her friends and family. That moment they share together at the end is just downright touching, for me personally as my grandmother Lois is currently ailing from dementia and staying at a convalescent hospital. Usually, the parent dies before the child, but the irony of the child dying first is another essential characteristic Nolan contributed to in this film. The advice that the old Murph gives Cooper at the end is pure poetry and unforgettable, leaving the audience shedding tears of joy, including myself.
So in conclusion, Interstellar delivers generally because its a story about the way we feel for others we love that wouldn't give them up for anything, not even a silly mission that is considered a mandatory task like saving the world from famine or finding a new place for humanity to thrive. Family comes first. And that's what I love of this film.
