A great subject idea damaged by the plot and saved by Zimmer

Rating: 5/10 (6 November 2014)

Even the title Interstellar evokes greatness, and the movie express this greatness through terrific photography supported by great picture quality (go to IMAX 70mm) and definitely communicated by soundtrack. Nolan knows that when you have Hans Zimmer on board you have an insurance: with his music you can transform even your dog daily service in an epic movie. Moreover the movie has a wonderful editing which give a great pace to the story. 9/10 on everything up to now. But when it comes down to the plot we barely reach 6/10. I will never understand why those Hollywood mega-productions that can do everything and have all these great subjects cannot avoid to make trivial mistakes across the plot. While looking at the movie it is like realizing that some good person had great ideas starting from the subject following with great details like the dust, the robots, the hibernation beds, and then somebody comes and place here and there some very simple mistakes. Here some:
First of all,the whole thing does not add up: the first time Cooper leave earth, who sent him the NASA coordinate?? NON SENSE.
second, at the starting of the movie you know the ending because too much emphasis has been placed on the message 'STAY'. I understand it adds a lot of drama to the departure scene but really spoils the ending. From there on you are only curious on how he will communicate back, which became clearer while watching the rest of the movie.
Third, I loved the transition between the departure from home with the truck and the rocket launch BUT wait a moment. Three stages Saturn V rocket to reach the Earth orbit (..OK they were using spares from Apollo mission..OK..) and in all the rest of the movie these guys land and launch from 3 different earth-like planets by using simply the small spacecraft??? C'mon.
Fourth, OK, you are trapped and the only person who can save humanity by communicating through time and what is the first thing you send to your daughter? Of course binary coded coordinates of NASA installation!! Not your name, not her name, but coordinates of the NASA launch site, so that the younger-yourself can LEAVE!If only all that you want is for him to STAY which is what you will send immediately after. OK maybe he do not know that he, him self, will start the whole thing just by following those coordinates..:/ WTF!!why?? Guys, I can understand you need to send Cooper to NASA, but couldn't you find something else?
Fifth. This is minor, but really annoys me that in 2014, in the Interstellar production, you, screenwriters team, need AGAIN to make someone to slide and fall and trap her leg to create AGAIN the run-for-it-but-I-cant scene, on a planet in which every minute is a year wasted in the search for humanity salvation and to bring back some unknown data!? C'MON!
You guys, have the best technicians and movie artisans, can afford almost everything you like, then again, why you have to slide on the banana peel? I will never understand.
