I don't work as a physicist (but I got my degree in Engineering Physics @ CU-Boulder, 2009) and I went to see Interstellar in IMAX on opening night. I really enjoyed it overall, and the scenes involving the realistically-rendered black hole were worth it alone.
I'm relatively easy to please when it comes to movies, but to each their own of course.
EDIT: Another physicist friend sat through it, but he said in his defense he was drunk and fell asleep.
