A brief, spoiler-free Deathly Hallows comment

My sister told me that some people, mostly those who had not read Harry Potter and the Deathly Hallows, found the new movie to be a bit slow.

Me: Yeah....I don't remember all that much happening in the first part of the book. It's more toward the end.
Sister: What? Blah blah happens, and then blah blah happens by page 15.
Me: Blah blah?!?! What? No!
Sister: Yes. Blah blah. Don't you remember?
Me: No...I must have blanked that out. Blah blah. That's awful.
Sister: And then blah blah, about a quarter way in.
Me: Awwww, no. Not blah blah. That sucks.
Sister: You did read the book, didn't you?
Me: Once. When it first came out. I remember the end, though.
Sister: You remember the last 50 pages. What about the other 709?
Me: Well...there was a lot of searching, and travelling, and talking, hmmm. Maybe I read it too fast. I need to slow down and pay attention. (Pause) Blah blah? Really?
