The Martian - The Swiss Cheese of Films

Just a few of my issues with The Martian. Spoilers, obviously.

1. The version of the human race in the film has had the foresight, ingenuity and money to start a colony on Mars, but they couldn't tie a guide rope between the spaceship and the base, or between each other. You know, like climbers have been doing for centuries. It didn't have to be a low tech hemp rope, it could have been wound kevlar, but no, nothing. And so Matt Damon gets blown away...
2. But not that far, and yet the rocket takes off and he doesn't get burnt to a crisp. In fact there is no evidence of the rocket taking off at all...
3. But taken off it has, and then shoots off back to earth. No "Let's hang around for a bit in case he's not dead?" Or "Why don't we just press pause on the return to earth procedure in case we need to go back to Mars?"
4. The version of the human race in the film has had the curiosity to start a colony on Mars, and yet they are not curious enough to have a look at what might be left behind on Mars, what damage might have been done during the storm, or if Matt Damon was really dead, you know, useful stuff.
5. Eventually they do have a look, 51 days later. And what do you know? Matt Damon's not dead. It will take over a year to prepare a ship and get it to Mars, so they turn the spaceship around and get back to Mars in just 51 days... no wait, they don't, and so the film continues.
6. So Matt Damon wants to communicate with Earth using Path Finder, great, lets use our modern radio systems and modern computers to... no wait, we have to *physically* go and find and boot up the old Path Finder machines.
7. Using hex to communicate through Path Finder. This is *so* inefficient, you're using 16^2 possible combinations for a possible 26 characters.
8. So eventually they do decide to send the ship back, but wait, it doesn't have enough fuel, everyone is scratching their heads until the stereotypical loner genius has an idea! The slingshot! This is the worst moment of the film. I honestly nearly stood up and screamed "Of course! The slingshot!" The slingshot has been done to cliched death in science fiction and was first used in real life by the Marina 10 probe in 1974. This is probably why no one mentioned it, they all thought it was a bit passée.
9. There are some women characters, but they still get a lot of patronising mansplaining.
10. The film ends and Sean Bean is still living.
