But there have been good teasers done before without giving away the plot or story. The Matrix, Cloverfield, Terminator 2, The Force Awakens, Alien(s), Back to the Future, Toy Story 4, etc. all put out really effective and good trailers.

My opinion, which is weirdly strong on this, I get it, is that they should do at least something to try and overcome the buzzkill that was the most recent Ghostbusters movie. This didn't do it. At the very least, zoom in on Bill Murray saying or doing something that is a throwback to the first movie.

Again, just my opinion on the teaser itself. Not meant as a slight on you for posting it (Unless you are the one who filmed/produced it I guess).
