My depiction of a real life phenomenon that happens in space, when in a binary system of two massive stars, one dies and supernovas first, the other sometimes gets slowly consumed by the black hole left behind by the dead star.

Oh gawd yes!
Like, do these people not even know the most basic thing about blackholes, aka they consume everything around them? Not to mention the intense radiation they give off...
The entire time watching it I was just thinking how idiotic that was, like why would think a planet orbiting a blackhole was a good place to colonize?
Heck what are the odds of a habitable planet (in terms of temperature and such because everything else, pbt!) orbiting a black hole anyways?

The only heat and light those planets would receive would be from the accretion disk. Now, it is theoretically possible for a planet to orbit a black hole at JUST the right distance to not be torn apart and receive the same amount of heat and light as Earth does...but the vast majority of energy emitted from an accretion disk is UV and X-Rays, which would strip any planet of its atmosphere.
Plus...Earth was succumbing to climate change and needed to be evacuated. The scientists in the movie spent DECADES searching the cosmos for a new home...and THAT system was all they came up with? Why not, say...Proxima B? The Trappist 1 system? Heck, MARS would have been a more viable option.

Right and yeah, not to mention be bad for any carbon-based lifeforms in the area
Yyyyyep! Thought about that too, and if they can travel that far then there should be loads of desirable planets within reach, and most movies like this do have people colonize Alpha Centauri, Mars, sometimes even the moon, but with the number of stars and planets within thirty light years alone they can’t just say they were desperate and had no choice since literally just anything would a better place to live than a friggin black hole

The space ship they built took the crew to Saturn in just a few months, so why even bother with a wormhole? TITAN WAS RIGHT THERE. Sure it's ludicrously cold on Titan but it has a thick atmosphere and a fluid cycle, it would have been a START.
And at the end of the movie it was revealed they decided "Eh...we don't need to go through the wormhole. Let's just build some space stations in our own Solar System."

And again, Mars, most ideal place to colonize and terraform in the solar system! Heck even the moon is a good first start
Yeah but at least they justified the reason they couldn't as being not being able to create artificial gravity, which would create a challenge for a long-term colony...don't have that problem with blackholes though! Nope, nothing to worry about there at all
Never made any attempt to explain why they chose a blackhole of all places instead of just a normal nearby star system

Yep!
Well lower gravity than Earth but Mars is still the best option if nothing else is available.
If you're desperate for a colony your best choices are: an orbital station, your moon, the nearest planet, the nearest star, and the absolute worst choice would be around a black hole or similar object, especially when you have literally countless others around to choose from.

Solar energy on Mars, while half that of Earth, is still enough to power all the rovers we've sent there, and the lower gravity in theory should still be enough to support human life (though over generations Martian humans would likely grow much taller, lankier and their circulatory system would change so much that returning to Earth gravity would cause serious problems.)
Also Mars has plenty of natural caves that could serve as starting points for underground habitats, and we can now 3D print extremely durable cement-like material out of Martian regolith. And, like Mark Watney in The Martian, it has been proven that if you add some fertilizer and rinse out the poisonous perchlorates, you can grow crops in that soil.
Plus, humans so far are a lot better at ADDING greenhouse gasses to atmospheres than removing them. Heck, the entire reason Venus's surface is the literal definition of Hell is the end-product of what we're doing to Earth unintentionally. Mars, by contrast, suffers from the exact opposite problem.

Ahh, and yep!
Mhm!^^
Yeah saw once that Martian soil reacts to water (I think it was water but still) in a similar manner to fresh soil on Earth, while sterilized Earth soil carries no reaction (interesting implications really..)
Of course! Changing Venus' atmosphere would take a lot of work and probably technology we don't have yet, while with Mars all we'd need to do is heat it up, even using mirrors to reflect the sun's rays at its poles would be enough to release carbon dioxide into the atmosphere, which will help to increase the temperature and pressure simultaneously (redirecting a few comets can add a bit of extra help too). Then you can just use plants or filters to create more oxygen and things are already looking good!

The ONE proposal that was made for teraforming Venus...was to completely block out the sun with a dish larger in diameter than the planet itself and maintain said solar shield for centuries until Venus cooled down enough for the CO2 to condense as rain and then freeze into dry ice.
For mars, space mirrors would be similarly difficult (plus even all the CO2 and water locked up in the ice caps would only increase the atmospheric surface pressure by maybe 30%...and it's currently at 1% that of Earth's, so not nearly enough), and while on paper crashing commets into the planet to generate heat and deliver new water and nitrogen MIGHT work...you wouldn't be able to send any missions to the surface for centuries until the rocks stop raining from the sky.
Plus...scientists calculated it...it would take, and I quote...ONE MILLION comets the size of Mount Everest to deliver enough material. ONE...MILLION. We would have to attach rockets to half the ice-rich asteroids in the asteroid belt and send them hurtling down to Mars.
As such, now the proposed method is the easiest and most obvious one, since we're already doing it on Earth; make huge pollutant-belching factories on the surface to mass produce super-heavy, super-greenhouse gasses like Sulfur Hexafloride, which is something like 50,000 times more potent e greenhouse gas as CO2, and because it's so heavy it would cling to the ground and pool in the low-lying areas where underground ice is most likely to be found, AND it's not easily broken down by UV radiation so once we make it on-site, it's staying there for a looong time.
