Oh, I'm not falling for this trick again.
Because of Rifftrax, I own and watched all 4 seasons of Heroes (should've stopped after the first season), the first 6 seasons of Grey's Anatomy (should've never watched any of it), and the first 6 seasons of Game of Thrones (before it got too stupid to continue watching, but in retrospect should have never watched any of it. Ugly, soul-destroying violence-porn.)
Manage to avoid watching the pilot for Lost, helped by the fact that even fans thought it was a waste of their time after whatever happened in the ending.
