Yeah, the characters were a joke. The dialogue was atrocious. I have no clue what Nolan was thinking when he made this, he's such a good filmmaker, but this.... This was really bad.
Yeah, I also disliked The Dark Knight Rises and Interstellar. Haven't seen Dunkirk, as I don't generally enjoy war films and as stated I was disappointed by his previous two offerings.
I've seen the rest of his filmography sans Following. The last good film he made was Inception. He had a great run up to that point, with The Prestige being the best of the lot.
I'll watch it some time, and Following. For completionist reasons.
I suppose he's never had a terrible movie, when compared to the vast majority of films, but given how great some of his work is, he's held to a higher standard by fans.
