Not scientifically accurate ... ( not how wormholes / black holes function.) but the third act has some interesting visuals . But this movie is overlong and overrated . Nothing on Kubrick. Its a stretch but some parts are still enjoyable. This could have been much more . More could have been explained with what happened to the ecosystem ... what about the the change of mental state through epochs ?. That alone could be a interesting movie ... hawkings talks about ideas that should be in movies but haven't been implemented. ... Yet!.

Like inception this movie deludes the audience with tantalizing concepts not fully conceptualized... but could be a spring board for future film makers ... sometimes i am let down by movies that promise too much . Some 13 year old is gonna think they have just had a quantum physics lecture ... ( sorry if i sound too harsh.) ...its less context and more deconstructed simulacra ...
