Thankfully, James Cameron is doing some great work by retrofitting an all time classic - Titanic (1997, starring Leonardo DiCaprio, Kate Winslet) - which is out in cinemas now as Titanic 3D.
A YouTube upload has somehow managed to make this even better, by imagining what it would be like if George Lucas, J.J. Abrams and Michael Bay were allowed their input...
Actually, maybe that's too much. Can't we just go back to good ol' fashioned Smell-o-Vision?
Because, as we all know, 3D is a sinking ship.
