Way back in 2007, when things called "blogs" were a daily read for many, I posted: My Top 5: Movies That Give Me The Danny Gut.
(I'll let you read the definition of "The Danny Gut" for yourself at this link.)
Anywhoo, The Danny Gut strikes when I love a movie, but it causes me emotional pain or discomfort. I got it watching Glengarry Glen Ross. I got it trying to watch Requiem For A Dream. I nearly died from the disorder watching Death Of A Salesman.
And I got hit with the bug big time while watching Nightcrawler.
Dan Gilroy hit a home run with his directorial debut. Nightcrawler is a masterpiece. Jake Gyllenhaal channels a little Travis Bickel in his creation of Lou Bloom, a character the audience can empathize with but can't allow themselves to like.
I liked Lou during sporadic moments -- a few seconds here and a few seconds there -- during the flick. And I hated myself for allowing that to happen.
It's that combination that causes The Danny Gut.
