Seen it on the big screen last night. Got my hopes high. Well, entertainment value
nill. I'm sure though it may appeal to the scientific community but as far as I'm concerned I tend to go to the movie to relax and be entertained. If I ever wanted to read a book on blackholes , relativity, time dilation I'd do just that.
Gardians of the Galaxy:
docking sequence 3s + 15 min of shooting people. Now were' talking
Interstellar:
Docking sequence 10min + ... .... ..-.. --..-..-- ?!
I'm clearly not the target audience. I had more fun listening to a raccoon talking to a tree

I'm sure there are people who will love it though.
The more scientific type will chime in I'm sure.
