:: Monkey business still pays. “War for the Planet of the Apes” took down “Spider-Man: Homecoming” at the North American box office, opening with an estimated $56.5 million in ticket sales.

Though some initially expected a closer race, “Spider-Man” dropped to second with $45.2 million after its $117 million debut last weekend. But director Matt Reeves’ “War for the Planet of the Apes” pulled away thanks to strong reviews for the third installment of the rebooted “Apes” franchise. Led by Andy Serkis’ celebrated motion-capture performance as the ape leader Caesar, “War for the Planet of the Apes” won a 94 percent fresh rating on Rotten Tomatoes.

Fox’s “Apes” led something of a summer anomaly: There is an unusual confluence of acclaimed films in release. Five of the top six at the box office (“Apes,” ‘‘Homecoming,” ‘‘Baby Driver,” ‘‘The Big Sick” and “Wonder Woman”) boast Rotten Tomatoes rankings of 92 or better, and the sixth (“Despicable Me 3”) was largely received as a solid enough family release.

Summer, rarely a critics’ paradise, is suddenly flush with good movies.

“What I think sets the ‘Planet of the Apes,’ these three films, apart from other franchise films, is that it’s not gratuitous sequel-itis,” said Chris Aronson, Fox’s distribution chief. “This is storytelling, and it’s episodic storytelling. It’s not ‘Well, let’s put the band back together.’ “

But there were also hints of franchise fatigue for the “Planet of the Apes” series. Reeves’ latest edition came in closer to 2012’s “Rise of the Planet of the Planet of the Apes,” and well below the $72.6 million debut of 2014’s “Dawn of the Planet of the Apes.” The film, which cost about $150 million to produce, added $46 million from overseas. (“Spider-Man: Homecoming” was still king overseas, where it added $72.3 million to bring its global haul to nearly $500 million.)

Aronson believes the good word-of-mouth will carry “War for the Planet of the Apes.” ‘‘At the end of the day, we’re going to have a terrific multiple and it will be a lot closer to ‘Dawn’ than it will be ‘Rise,’” he said.
