Al Pacino's accent blows, yes. Most people latch their feelings of its time of release to Christopher Nolan's re-working/remake of Insomnia. I thought it was perfectly serviceable then. It wasn't staggeringly great, but it was a good "studio picture with name actors" under the belt for Nolan. Re-watching it on Blu-ray the other night (and without having seen Inception), I really found myself favoring it a bit more than I'd recalled.
Maybe it's seeing and loving the craft inherent in the rich in-camera captured contrast and color timing. Most people don't fully perceive how much contrast and color work is shuffled to the territory of "we'll fix it in post with a computer". I haven't watched tons of extras on this stuff and been told this, but I can tell the difference between natural light and color and "retouched" stuff. Most people innocently comment on the quiet placid vistas of a movie shot like Insomnia by saying "wow, it looks like Discovery Channel HD" and moving on.
On top of the extras, Nolan devotees who buy this are rewarded with an "up to $7.50" voucher toward a ticket to Inception. I'm hearing good things about it (and some lukewarm, and some bad), but I want to let the crowds die down a little. Even as an avowed fan of the Batman character and mega-franchise, I waited weeks to see The Dark Knight quietly and politely at the local IMAX for my first viewing. I didn't want a chorus of adulation artificially coloring my reaction or enjoyment.
The $17.49 asking price on Amazon is a bit outside what I'd call the comfort zone for most catalog Blu-ray buyers, but the movie cash voucher makes the "real price" to someone going to Inception (the first time or again) ten bucks. Most people probably wouldn't do that math in the seconds afforded to impulse buy at retail.
