There are sequels that fans get rightfully excited about--The Empire Strikes Back, The Godfather Part II, Breakin' 2: Electric Boogaloo--and then there are sequels that fans of the original movies probably don't even know exist. In most cases, that's probably a good thing. This week's video Inventory covers some of those crappy, crappy movies that besmirch their forebears' names: We're talking S. Darko, Revenge Of The Nerds III and IV, and The Cell 2. Didn't know there was a Cell 2? Didn't care that much about The Cell in the first place? Exactly.
