Time Sensitive

We all have them. "Those" movies. The ones we will never (nevah), ever (evah), under any circumstances, watch again. Movies so bad or so inept that we can't imagine wasting another minute of our lives watching them. Movies we've walked out of, turned off, or even worse, miserably sat through their entirety. Does one of your favorites make the list? (Excuse the fireworks going off in the background)
