Today the full Ghostbusters trailer has been released, and it's explosive. You'll see Slimer. You'll see the proton packs. You'll see the reason why these four actors were chosen for their respective roles. You'll be reminded of the original Ghostbusters in the best way possible. And there'll be a lot of special effects - so many that you'll forget what made the original Ghostbusters so excellent and memorable. This is a whole new generation, after all.
