It's somewhat sad that this category even exists, but given the sheer number of remakes, reboots and sequels out there these days, we actually have precedent to decide which project is the MOST unnecessary. In 2012, that award goes to Total Recall.
Early on, the filmmakers promised that this redo of the 1990 Paul Verhoeven version (starring Arnold Schwarzenegger) would actually stick closer to the heady themes and ideas of the short-story by legendary sci-fi writer Philip K. Dick. However, what we got was just another mindless action flick - one with less ambition (and space travel and mutants) than Verhoeven's film.
Really, the only thing that Total Recall 2012 accomplished was adding another bothersome entry to our IMDb search results.
