Upon second viewing:
The first scene in the movie is so awesome. Think I already gushed about it, but it sets up Toomes and the "bad guys" so well. Of course what they're doing is wrong, but I like that you feel for them, too. Everybody's been screwed before, and that's exactly what happened to the salvage crew here.
There's a subtle homage to the finale of Spider-Man during the ferry scene. As everything begins falling apart after the first web snaps, Peter lunges out holding one web to grab the other and attempt to keep the ferry from falling apart. The pacing, the breath Spider-Man takes, the angle...it all reminded me of the scene where Spidey swings with one hand on his web and uses the other to grab the falling tram car in the first Raimi film.
