Easy YES for me.
I usually find myself agreeing with points raised by both Amy and Devin. But I've never disagreed with Amy more than on this episode. I found her problems be very nitpicky or a misreading of the film.
Pitt plays Mills as braggadocious, not dumb. He's self-assured and brash but recognises he's out of his depth. He reads the Cliff Notes, hence the dialogue;
SOMERSET: Did you read them?
MILLS: Yeah. Parts of them.
He moves the conversation along quickly - not wanting Somerset to enquire further and determine that he cheated and read th Cliff Notes version. This is great character work (Mills developing as a detective and learning off of Somerset) while adding some humour to the scene. Even though the film is dark, there are lots of moments of levity.
Amy seems to feel like the audience needs a scene where we watch Mills sitting and reading the Cliff Notes. Pretty boring. I'd rather the economic and funny way that info is communicated in the movie.
Same with the empty aspirin bottles. Does every piece set dressing in the apartment need characters pondering aloud to John Doe's purpose? No, I'd prefer the film to hint at these things and tie into the great dialogue/performance from Spacey in the back of the cop car. It's all a game and puzzle to him.
Seven is a great film. And it lead to a great episode of the Canon.
