This is a different market than when the first set of movies came out, the novelty factor of superhero movies is gone, now people just want to see a good movie. Homecoming was a good movie and is one of the few bright spots in an otherwise dismal summer at the box office. Planet of the Apes tool a calculated risk to release kneweek after Homecoming, and paid the price big time at the box office, but still likely took a bite out of Homecoming's second week numbers. And still, it's shown to have long legs. Marvel not only showed Sony to make a good Spider-Man movie, they showed them how to make a smart one (financially speaking). It's been said that Spidey's extended intro in Civil War likely pumped $100MM extra into that movie's coffers. Homecoming will likely end with between $820-$850MM, which is a fantastic multiple and a very good result for a solo hero project (particularly one on his sixth individual outing in 16 years). Those are numbers very close to what Wonder Woman will do, and that's with the advantage of releasing earlier in the year against no or weak competition for a solid month, and near universal critical and SJW fawning, and being Wonder Woman's first solo movie ever in that character's 75 year+ history. With that individual novelty now worn off time will tell how well that character "ages" on the big screen, particularly after what is likely to be an extensive appearance in (if early reports are any indication) a really terrible JLA movie. Regardless of all of the non-stop heaps of acclaim , I still find Gal Gadot miscast for that role, the movie overly long and tedious, narratively disjointed and choppy and the SJW themes of the movie as about as subtle as a jackhammer to the side of the head during nap time. Meanwhile I found Holland's performance genuinely wide eyed and earnest, and perfect for the MCU. While that movie was also 30 minutes too long, and too jokey (a problem I have with almost ALL marvel movies) it at least had a smooth narrative and one single compelling villain performance by a great , seasoned actor who nailed it.
