Depressing movies that you only watched once....
Passion of the Christ. At one point it was so gruesome and graphic, that I walked out. Couldn't handle it. I know the movie was trying to make a point, but nobody needs to see chunks of flesh ripped out of Christ's back by metal hooks at the end of a rope/chain.
A Star is Born, the newest version with Bradley Cooper / Lady Gaga. Good movie, good acting, storyline keeps you engaged. But at the end the movie rips your heart out and stomps on it. I left the theater just feeling like I got punched in the gut. So sad.
