"Similarly, as a visual medium, showing things happening rather than explaining them has much more impact."

I agree, but here's one of Hamilton's complaints:

"I'd barely gotten my head around the fundamental framework of the host/architect/subject relationship before I was being told about "totems" that anchor dreamers to the real world and "kicks" that wake them up..."

Nolan showed some of these things visually in the opening sequence before explaining them explicitly when Page was introduced: an architect (Lukas Haas) had introduced himself; we were shown what an architect is supposed to do (the wrong carpet); and we were shown a "kick". I thought these things were fairly intuitive, but it's a good job his script exposited them explicitly, or apparently Hamilton would've been completely lost.

Perhaps sometimes a little weak storytelling is good for the audience.
