In a lengthy caption, he delivered an honest and hilarious review of the Backstreet Boys Live at Sphere Las Vegas.
Apart from this, he also revealed how Song got emotional and overwhelmed by the nostalgic energy of the night.
“Mack Street’s Back, ALRIGHT!!! Hey y’all, remember the ‘90s? Just went to the @backstreetboys at @thespere this Saturday and Brenda lost her sh*t. (She literally cried).”
Moreover, Culkin was also impressed by how the group managed to deliver such a spectacular and high-energy performance, even in their mid-40s to early 50s.
“I was mildly skeptical about the show, but boy howdy did they tear the place down,” he said, adding, “I was so very impressed. Five minutes into pilates, I’m toast. I’m 45, but these men, who are my age, GO at it HARD for 90 minutes. Nothing is wasted; they use every part of the buffalo. Top to bottom, head to toe, floor to ceiling, soup to nuts, beginning to end, it’s incredible. They got it. They got it more than ever.”
The comments section also lit up with fans praising his genuine excitement.
“Best possible review of any show, ever!” one wrote.
As for some, they gushed over how the post was giving a major ’90s vibe with Culkin and the BSB in one photo.
“BSB and Mac, didn’t expect to see both my favorites in one frame!” a follower said.
“Peak 90s nostalgia all in 1 photo,” another added.
On the other hand, Culkin’s post didn’t go unnoticed as Richardson commented with a red heart emoji, showing his appreciation for the actor’s heartfelt support and enthusiasm.
Based on posts shared by fans online, Culkin was absolutely right—’90s boy bands went all out, giving the crowd a night to remember.
