Why do movie makers treat audiences like idiots?

Elysium is an OK movie for people who want to check their brain at the door, or watch 2 hours of visual effects eye candy. It looks great, but the movie makers treat the audience like brain dead idiots. There are so many plot holes in the movie that I gave up counting.
Even worse though, there are huge glaring scientific errors.
Elysium is big space station shaped like a spinning wheel. It's inhabitants live on the inside of the wheel getting artificial gravity from centrifugal force. The "top" of the wheel does not exist. It's not closed or sealed off in any way so other space ships can come and go. There is nothing to hold the atmosphere in place. GLARING TECHNICAL ERROR!
The spaceships come and go and land on the inside of the space station near its edge, where it should be spinning its fastest. GLARING TECHNICAL ERROR! Any ships would have to enter and leave from the center hub of the wheel, not the edge.
In order for Elysium to remain in space it would have to be in a Geostationary Orbit which is 22,236 Miles above the ground. Small spaceships lift-off from the earth and travel to Elysium in only a few minutes meaning the ships travel at over 7,000 miles per hour. GLARING TECHNICAL ERROR! Forget the fact that the occupants suffer no G-forces, that the ships couldn't possibly carry enough fuel etc to get there or get there that fast, etc.
I'm no scientist and I'm no math geek but this kind of stupidity in a movie has to go.
Oh and if this isn't enough, the movie also has characters that look at computer screens of pure random gibberish and suddenly realize that "This is the code that will save the day!". I mean it - except for maps and other flight data once in a while, the most important computer screen showing the most important data that is the most important part of the whole movie is just showing garbage - random characters - crap - nada - nothing. WTF, movie makers?
Sure the movie is "just" sci-fi and sure it's "just" fantasy. But really how much does it cost to hire a science consultant so that idiot stupid BS mistakes don't slip into your $150M movie?
Attention movie makers : Hire me and I'll make your sci-fi 10 times better by stopping you from making GLARING TECHNICAL ERRORS in your films.
