THANK GOD it's another origin story, because we so badly needed one after ten years...
Seriously, what's the point in retreading old territory with an origin story? Why can't he just be Spider-Man from the beginning of the movie on? Gritty Spider-Man? When I think gritty comic book characters, I think Wolverine, Batman, and Daredevil. Spider-Man is not gritty. He's a guy who cracks jokes when he's fighting bad guys. He's had plenty of dark moments to be sure and the death of his uncle is one of them. But he's not the Dark Knight and this shouldn't be The Dark Knight.
Andrew Garfield is a great actor but he still looks a little too old to be playing high school Spider-Man.
Finally, I don't see what the fuss is about this trailer. It's Spider-Man Redux on the big screen.
