Perhaps you went in expecting some sort of scientific documentary. I went in expecting a great movie with some real life concept of general relativity applied. Do note that I am not a physics or science major, for that matter.
I did study physics and I did generally enjoy the film, but that doesn't mean there are so really stupid bits in it. I didn't expect a documentary, but what I got was half a documentary and half a drama of sorts. But kind of forgot what it was half the time.
I have no issue with weird stuff inside a black hole, but what was there was just so stupid. Then we get the speech about love being the 5th dimension which just made me angry
The real physics issue that annoyed me was the lander. To leave earth, they take this huge rocket to reach outerspace with no problem at all. Yet this tiny lander has enough fuel for 2 planety landings and take offs, in planets that have strong gravity. It just doesn't make any sense
My point with this is if you spend 90% of the time with "hard sci-fi" and then you get lazy, that really annoys me.
But that's not my real problem with the film! The real problem was that the dialogue was poor and everything just felt a tad sloppy. All the scenes on earth took twice as long as they needed to, I just wanted them to get into space. When they did, WOW! The imagary was just fantastic and then the plot kind of fell apart again...
If you're looking to settle humanity on a planet, why would you even consider the first planet? It's so close to the black hole that it's simply not going to be stable. There was no reason to go there other than to speed the plot along. These guys are scientists, they're not stupid! It just doesn't make any sense
I didn't think it was a bad movie, but I certainly wouldn't recomend it.
I'm no Nolan lower, I think the Dark Knight Rises is just one giant plot hole and Inception is not a masterpiece, merely a good film. Memento on the otherhand is a master piece. But yeah, I wouldn't go see this film again
