Agreed, Spidey is the last movie my family and I will be paying for this summer. Movies are simply too expensive to justify going unless the people producing the movie have earned it.
The Lego movies are another good example of what happens when you water down your product with bland or outright bad movies. The first one was an absolutely brilliant movie. The second one was pretty good. In between those was Lego Batman and Ninjago which were underwhelming and awful respectively. That lost people's trust and Lego 2 paid for it.
