When you realized it was fake

I think that the tag line, "Based on a true story" isn't entirely without merit. Take The Texas Chainsaw Massacre for example: It was certainly inspired in part by Ed Gein. The events in the film are fictitious, but are in fact inspired by actual events. Ed Gein was notorious for snatching bodies, mutilating them and taking skin and body parts as keepsakes. So, it's not necessarily all bullshit, especially since the tag line fails to specify which particular story that the film is inspired by. Wolf Creek is another example, but then again, Wolf Creek was also inspired by The Texas Chainsaw Massacre, just set in the Australian Outback. Granted, you still want to take it with a grain of salt, but don't dismiss that tag line entirely.
