First of all I am not an expert in the field of spiderman if ever.
The first thing that came to mind watching the trailer is fucking the animation is badly bad you could believe that it is a film at first glance.The music is very good it leads to a good pace , and we can see A spiderman turn around we see immediately that this is not the costume we are used to.It is seen that the character wears many NIKE sneakers will shout at product placement but personally I think it's for better integrate the character as if it was part of our reality can be seen from the cars that can be seen and are also marked. The class of the character when he propels the building with shards of glass, the slowing down during his fall, the impression of speed, everything is mastered in this sumptuous scene. We are told directly that there is not only ONE spiderman but many in this universe so we can imagine that the film will explain why there are several otherwise it would be a great disappointment even if it is very not very propitious that they do not answer this question.
We have a scene of pursuit between two spiderman with an alternation between very realistic animation and an animation in comics that is a nice wink to the original work. Finally we can see two spiderman chat with each other and one asks how much they are and we can see a little spider on a pillar that may be causing all that.
To end in this trailer we have no information on the screenplay except that there is not a single spiderman, we do not know who is really responsible for all this (can be the spider or something else or someone) we do not know who is the villain, who are the characters he will have to wait to learn more and to see the complete fim it will be necessary to wait for Christmas 2018 (for the moment).
