It's good to indulge those ideas where you can. There's a bug in my brain from the one minute of the movie I've actually seen so far... but I do think that I probably ought to see the rest of the movie first. I'm well spoiled about it, and happy to be so, but there's a lot that can go wrong if you make assumptions based on a synopsis.

(In case you were wondering, the minute in question is where Peter has a chat with his Really Good Lawyer.)
