In theater we typically sit back, relax and then watch movie, but this time rather, it looks like we are in a class to understand complex science lessons such as Schrödinger equation or Quantum physics. Interstellar was the first film for me in which the need of pen and paper arose.

Regarding knowledge and entertainment: Little bit of education but 0 for entertainment. One must watch movies like Pirates or Avenger to neutralize hang over of the movie like this. During the starting credit the film should show Disclaimer like: "Only for science people". We are aware of the astronomy terminology used in the film like event horizon, time dilation, black hole, Einstein theory of relativity etc. but not all. Movie fails to entertain many of the viewers.
