5. Crappy Movies
...if they keep producing bad movies. "Hollywood is dumping garbage on us (in the form of sequels, prequels, remakes, reboots and franchises which we didn't ask for or even want, not to mention having 3D slapped on every movie in sight), calling it 'collective art' and expecting us to pay for it through exorbitantly high ticket and concession prices," wrote Stepahnie Freeman. Which might be the biggest sin of all. To paraphrase Robert Reich, "It's the movies, stupid." That doesn't necessarily mean audiences only see good movies (har!), but that audience-interest is almost more important than quality. You can get people out to the theater for 'Harry Potter' and 'Transformers'; you'll have a harder time getting them out for 'Green Lantern' and 'The Thing.' General audiences aren't perfect -- the customer is always right until the customer ignores a great film like 'Warrior' or a pretty-good one like 'The Ides of March' -- but they can still smell a dog (like the pictured 'Bucky Larson'). When they do, they'll stay away. In droves.
