!!!SPOILERS AHEAD!!!
I'm talking about the repetition of some scenes like "consultation with X character", "talk while walking down the street", and "talk in the cafeteria".
I believe that the entire research process took a bit longer than necessary due to these factors.
That's also why I had the impression that some of these felt a bit redundant, like the consultation with Elizabeth, for example.
There was a certain point where I think that the story could have moved on to the final act without experiencing these scenes again.
About the "I saw it coming from a mile away", I didn't mean negatively, in case you had that impression.
I just guessed what was going to happen in the end (except for the use of the winning torture device or the warning of Harry), thanks to the foreshadowing through the story.
