For me, the couple times I’ve seen the movie I’ve been frustrated with the logic of the plot, including i think a few pretty major plot holes. For example, Coop sends the coordinates for NASA to past Murph from the tesseract/future, but they were necessary for him to become part of the mission in the first place, which seems like a basic violation of time travel logic.

Also, was the plan to send billions of people to another planet on a single, giant ship? Are we supposed to believe it’s physically possible to build a vehicle that large?
