I enjoyed the movie a lot, the Power of Love thing was kinda lame, but I also thought that about the 5th Element and still loved that movie.
I agree they could have let up on the talking between Cooper and TARS a bit, but I don't agree that there was too much information given early. I think anyone who goes in at least knowing there will be space travel and can remember some of their high school science classes when it came to the lesson that gravity can bend time, will would guess what's going to happen fairly quickly. As soon as Murphy first appeared at the breakfast table and said there was a ghost in her room throwing stuff, I instantly thought, nah that's your dad from the future trying to talk to you. Fortunately I was distracted enough by the movie to forget that I believed that they had to be going into that black hole at some point.
I didn't really feel like Cooper was "The Omnipotent Dad" in that moment. Though the whole thing was very convenient and eye rolling, all he did was transfer information to his daughter through Morse code from TARS data. I had the distinct feeling the information was way over Cooper's head and only Murphy could do the math to make sense of it. She got the proper recognition for that. This is a movie that started out feeling like all the men were going to be the big damn heroes per usual, while female characters stand in the background quietly half smiling at each other and disappearing while the men have serious conversations. I'm cool with a handful of male characters being selfish assholes nearly wrecking everything in an attempt of making themselves feel like they are the important big damn heroes in the grand scheme of things. However I feel like there should have been a bit more of a boost for the heroines. The only scene I recall two women talking to each other is between Murphy and her brother's scenery wife. It would have been interesting character boost to have had Murphy and Amelia geek out over science together while the men were talking their important serious conversations. I had this fear for a bit that they were switching places, Cooper would become a proper father figure to Amelia, and Brand proper father figure to Murphy, and there would be some Electra complex subtext between Cooper and Amelia but things thankfully do not play out that way. I especially like that Murphy does ultimately make Brand look like a fool.
Also, the only black character still died in a really, really cheap death. Thankfully there was that somewhat racially mixed looking guy guiding Cooper around in the end, cause I would have thought all the white people abandoned the non-white people to die on earth.
In the end, the sound track has to be one of the worst soundtracks ever. I felt like my head was stuck in an organ pipe while someone played the same three annoying keys. When I was leaving the theater, everyone was complaining about how awful it was.
