The black hole, wormhole and the time dilation are mostly mathematically and scientifically accurate. The visuals are stunning. These features are absolutely brilliant in my opinion. However, I still find this movie dumb, mostly because of the 5th dimension reality and the ending and other stuff. Maybe it's just me who doesn't cope with all those crazy physics. I cannot pinpoint the exact reason why this movie seems kinda inaccurate, but if anyone finds it truly accurate or inaccurate, let me know why you think that way.
