Spinorial: Apparently Kip Thorne consulted on the appearance of Black Holes and they've done a sweet job with those. Too bad he didn't consult on matters of tidal forces and radiation emission :P
Well, Kip Thorne explicitly mentioned that with a rapidly rotating black hole (such as the one in the movie), a planet this close could still be in a stable orbit, without disintegrating into a ring (as opposed to a planet orbiting a non-rotating black hole). He also noted that the accretion disk was (for whatever reason) relatively weak and cold, hence low emissions.
What I don't understand, though, is how Cooper was not blueshifted-gamma-ray-ed into oblivion (by the light coming from behind) as he was nearing the event horizon.
