I watched it and I loved it. I don't think I can spoil it any more tbh, we all know how it ends :p.

Unlike other Nolan movies, I found that the plot wasn't too difficult to understand. There's some science. But it's mostly a historical political drama.

One thing to keep in mind is the switch between B&W and colour scenes. The B&W scenes require objective interpretation and colour scenes are subjective. I wish I'd known this before watching the movie

Watch it in a good theatre.
