It also annoyed me how Spiderman is the direct cause of pretty much ALL of the collateral damage in the movie. He's made out to be almost completely incompetent for the sake of some laughs, and I feel like it really takes away from the character.
For the sake of some laughs? Really, I must have missed that because what I saw was a movie in which this new superhero is being mentored by one of The Avengers with a view to gaining his skills, getting used to his new suit and being told specifically, several times through out the movie to keep to the small time stuff, like he was doing prior to Civil War, and that even when The Avengers aren't getting involved in the larger stuff their is still a system at work in the background to make sure the bad guys aren't getting away with it.
A movie in which Peter is so desperate to impress, so desperate to get the next call up to The Avengers that he gets in way above his head, i.e hacking the suit and taking the training wheels off, going after someone who was already on Stark's radar and as a result things go wrong.
This movie was an origin story but with a twist. Most origin stories spend the first act showing how they got their powers, the second act showing them getting used to their powers while ramping up the bad guy and the final scene is them coming to terms with their powers and beating the bad guy. This movie skipped the first part and spent most of it's run time focusing on the him getting used to his powers.
