Vintage cheddar or Swiss cheese?

Rating: 7/10 (14 April 2016)

Don't get me wrong. I really enjoyed this film and really wanted to give it 9/10. But I can't.
Simply, it is full of holes. Not just the black or worm varieties. Plot holes. When the film came out, it claimed to follow acknowledged theories of relativity, wormholes, black holes and interstellar travel and, in that, it made it true to expectations and 'plausible'. However, somehow the story-telling and the screenplay got in the way. There are incongruities, omissions, inconsistencies, vague assumptions, unrealistic assumptions. Just a few are:
If Coop were crucial to the space mission, why was he not contacted by the NASA team? (Why did it take him going back in time to give himself the heads-up as to the base's location?)
When the crew travel to Saturn it takes two years in hibernation. Why, after they travel through the wormhole, are they immediately in the proximity of the three planets they want to explore? (Or is it, having got the gist of it, we have to assume subsequent periods of hibernation?)
Spending an hour or so on the first planet results in 23 years passing on Endurance. Acknowledging the theory, at what velocity must they be travelling for their hour to be over 200,000 normal hours (23 years) when they return to Endurance?
To leave Earth, they need a Saturn 5 type rocket launcher. When they leave the subsequent planets, they only require the lander to escape gravity. How is it possible?
On the first planet, they knew that time would pass a lot quicker yet they did not figure out the scout beacon had only been transmitting for a few hours and not several years until after they landed. (They also would/should have known about the huge tsunamis raging across the surface.)
If the wormhole was created to help mankind, why was it created so far away from Earth's orbit?
Why does Professor Brand spend most of his life knowing his studies to be a lie. Could he not have used his skills to find other ways to save the Earth? Rather disappointing for such an intellect!
When Coop is in the black hole and the 'other beings' have created time in 3D for him which allows him access to the entire history of Murph's bedroom, why does he wait until Murph is 33? years old before giving her the information required to save the Earth? Also, how long would have taken to convey this information in Morse code on the second hand of a dicky watch? (As he only had a physical influence in and around his house, she would have had to stay in her old room to receive the whole data.)
When Coop is rescued and gets to meet his now ageing daughter, she tells him to go back through the wormhole because "Brand needs you". It seems implausible the she would know that one, Brand is alive on Edwards' planet and two, she would need Coop. A parting epilogue that Coop and Brand will find love and get together on Edwards' planet?
For such a long running time, it sure leaves a lot out. I could go on...
Unfortunately, its nod to 2001: A Space Oddessy and the profusion of 'science', in a way, sets itself up for extra scrutiny.
I am sorry if this gives the impression that it is not a good sci-fi film or my recommendation is not to watch it. On the contrary, watch it as a thought-provoking, science-based, rip-roaring end-of-the- world sci-fi with the right mix of science-fact, science-fiction, human frailty, sacrifice, romance and sentimentality. Awesome in scope and cinematic achievements, brilliantly scored by Hanz Zimmer, heart-warming and optimistic in its writing, a worthy sci-fi epic. Just don't ask questions along the way.
