Well, i'm just back from seeing this and as someone who actually understands the physics, a lot of liberties were taken for the sake of dramatic storytelling.
In the last half hour or so
our hero falls into a stellar sized black hole. The problem with that is a process called spaghettification. Put simply the tidal forces would have converted him into a long string a really long time before he passed the event horizon. It would require a black hole of the kind only found at the centre of galaxies, typically with the mass of several million solar masses, to have tidal forces weak enough for our hero survive to the event horizon.
Then there's the whole basis of the story, the wormhole that makes it possible.
You cannot actually have a stable wormhole, for them even to exist requires the use of something called negative matter. This stuff is different from anti-matter, its a whole different class of material and it generates anti-gravity. Space-time needs to be ripped apart and that's the only stuff that can do it. The Stargate series was more realistic.
One other little niggle which isn't going in spoiler tags this time. A black hole is a gravitational object. The only paths you cannot escape from are the ones that pass through the event horizon. Any orbit is just that an orbit. If your path passes into the event horizon then your best survival technique is adding sideways motion ASAP. If you're not passing into the EH and all you want to do is change your orbit so you end up elsewhere then you do so ASAP as that has the maximum effect on your path.
The story itself was a bit meh, I really hated the talking heads.
On the plus side, less liberties were taken in this movie than they did with Gravity, so i'm giving it 6/10.
