I just saw it a couple hours ago and I was amazed. Now, you really have to suspend disbelief for a lot of it... I am a mathematician and most of the math on the boards appeared nonsensical (they could have had at least somewhat accurate stuff like on "The Big Bang Theory" boards). And a lot of the astronomy stuff was a bit ridiculous, as black holes/wormholes/stars are SO hot and SO dense you would be crushed by the gravity before even reaching the surface of anything.
There was also some plot holes, cliches, and poorly written scenes. However,
I say I was amazed because of the beautiful imagery, even if it did seem Star-Wars-ish at some points. And the references to "them" and the higher dimensions, much of which was theoretically accurate, really made me think about some of my DMT experiences and some of the theories surrounding DMT. I think it's a great movie for anyone who likes to theorize about hyperspace, and because it matched up so well with my thoughts, I thought it was very relatable and cool. I would recommend it!
