I actually thought the concepts in the film were pretty well presented. I didn't find myself confused at any point during the film. Actually, I was somewhat disappointed. The Prestige was a film that constantly kept me guessing, and I loved it. Inception also grabbed me more and had me wondering how things would turn out. But in this film, I thought the "twist" was fairly easy to see coming. And I agree with Degrasse-Tyson [BLACKOUT]If the wormhole allowed him access to all dimensions, which allowed him to do things like move books or create lines in dust, why the heck didn't he just write out a note?[/BLACKOUT]
However, despite that, I really did enjoy the film. It was beautifully shot, and I was lucky enough to see it in a true IMAX down by Lincoln Center, which was great. I thought everyone acted their parts very well, and it was an intriguing story. However, it just didn't capture me the way the previous Nolan films have. TDK, Inception, and Prestige are three of my all time favorite films. BB and Memento are also up there. TDKR was the "worst" Nolan film I had seen, but was still very good. I would put Interstellar in a similar category. A good film, fun to watch in theatres, but I don't have any desire to see it again. After I left TDK, Prestige, and Inception, I instantly wanted to buy a ticket and watch it again. Same with BB come to think of it. There's just something this film didn't have that the others did. And I'm not quite sure what.
