Since this looks to be the next Spider-thread....here goes.

PROS

1) Holland. He's excellent as Peter thus far. That opening scene to the international trailer was 100000% Spidey
2) Keaton. I like the Vulture's look, he seems dangerous enough as a criminal ringleader.
3) The Shocker gang. I really like this concept, just a unique take on the villain.
4) The rapport between Peter and Tony. It doesn't seem to be as "buddy-buddy" as we thought. I think Peter's JOURNEY in this film will be trying to prove himself as an Avenger-level hero to Stark, before realizing he doesn't need to prove himself to anyone but HIMSELF. I know a lot of people have said so far they think it's wrong that Peter is so "subservient" or "desperate"...but I think that's kind of the point.
5) The high school environment. I know a lot of people don't like it, but it opens up a lot of potential for new stories. And unlike previous film series, this one REALLY wants to hone in on it....and it FINALLY looks realistic, at least in my view.

CONS/WORRIES

1) Keaton, but ONLY in the sense that I'm worried. Yes, his casting is great, but so was Mads' in Doctor Strange and he turned out terrible as a result of being underwritten. The caliber of actor does not matter if your character isn't given a proper focus. So I HOPE the Vulture is memorable/doesn't die.
2) "Ned Leeds". Just call him Ganke for godssake. He is Ganke, he's done everything that Ganke does and LOOKS LIKE HIM...it's stupid that they renamed him for no reason.
3) Tony. Again, a worry that he will overshadow the film. I was disappointed to see Iron Man, as INEVITABLE as that was. I get that Sony wants to market the MCU connection. It makes sense. I'm just not a fan of it. BUT there's a lot of context we haven't seen.
4) Vulture knowing Peter's identity. Again with this sh*t. I know the secret identity thing isn't a big deal in the MCU but Peter's should be. Ganke----er, sorry...NED knowing isn't a big deal but I just....for once...want a movie where an adversary doesn't need to know he's Spider-Man to hurt him.

Some things I noticed from the trailer as well:

Spider-man fights both Bokeem's Shocker and Vulture in his "proto-suit", not the "classic" suit Stark gave him. So either he fought these guys prior to Civil War, or something happens to his "classic" suit during the film and he gets another later.

You see the Statue of Liberty right behind Spider-Man when he's holding the boat together.

Peter is wearing the same shirt Pepper did in Iron Man 3 when she's surprised by the suit in bed.
