Another issue here would be time dilation. Generations could go by while the explorers attempt to explore the surface of the planet. It does provide for the stunningly terrifying idea that you could be on a planet and look up and see a black hole in the sky. I guess Christopher Nolan will have to incorporate it into his next movie.

It's a very interesting idea, but the time dilation effects from a black hole are no stronger than those from any other object with the same mass, so you have to be very close for it to be noticeable. Of course, in reality black holes have massive accretion discs which would mean no planets could exist very close to them for long.

Time dilation isn't that strong unless you are extremely close to the black hole.

The extreme time dilation in the movie Interstellar is not impossible but it's not realistic either.
