I liked the movie in spite of its flaws, one scene in particular that got me was the "drama" they tried so hard to setup. They cut back and forth between this scene and Cooper's struggles in an attempt to show the parallels between the two but it just doesn't work IMO. This is one area of Interstellar where Inception does a much better job. In Inception, the editing worked because it drew parallels between scenes that made sense. In Interstellar, it's just a distraction from whatever Cooper is doing. Nolan really dropped the ball by trying to use some of Inceptions' editing tricks in a film that doesn't really fit what he's trying to achieve.
Murph and Topher Grace's character arrive back at the old farm because she has to revisit her room and they show this big dust bowl/storm approaching as if shit is about to go down. So she revisits her room and Topher starts doing doctor stuff like checking on the health of the family. They get told to leave, but Murph gets the bright idea to come back because *THIS* time it'll be different, but first she has to set her brothers crops on FIRE. She then drives to the apparently now vacant home because her brother thinks it's a smart idea to take his sickly son and wife to a fire I suppose(?) So she's in the room waiting for something to happen and Topher is trying to generate drama by keeping her updated on the state of the fire. So she gets her answer from Cooper and heads outside where Topher is holding a tire iron because he's gonna hold back the evil big brother. Of course this all means nothing because she hugs the bad out of him and it only gets worse when she's running around the lab with triumphant music and yelling "eureka."
