Several Batmans and Captain Americas were spotted at the Dallas Comic Con this weekend, but the two superheroes were not match for the lines at the Irving Convention Center.
Event organizer Ben Stevens told NBC 5 that early counts show that between 18,000 and 20,000 showed up to the weekend event, well beyond what the show's website called a "hopeful goal of 15,000 attendees."
Squeezing thousands of people into the Irving Convention Center proved to be a problem of Hulk proportions.
The crowds was there to see actors from "Star Trek: The Next Generation" and other sci-fi shows, as well as Stan Lee, the co-creator of Spider-Man and other superheroes.
Stevens told NBC 5 that Lee and actor Patrick Stewart were at the show on Saturday but couldn't show up on Sunday. That forced die-hard fans to show up Saturday to get autographs.
Stevens said that he would like to spread the event out over three to four days in the future to spread out the crowds.
Some fans took to YouTube to rant about waiting in line.
A Comic Con pro who covers Comic Cons online and goes by the name Taffeta Darling said the show was a bit too packed.
"You know, we expected what we usually do -- go in costume and hang out and stuff -- but there wasn't any room to do that because there was an abundance of people," she said.
Darling said she saw many rookie Comic Con attendees and wanted to remind them that while dressing up and having fun at the events is a hobby for some, others make a living at the events.
"A lot of people who complain about certain things need to remember, it's a business, and if you don't have these people coming to support these vendors and artists, we're not going to get continue to get big names," she said.
Darling said vendors she talked to were happy with the crowds because they bought up memorabilia and sketches at premium prices.
Darling said Dallas Comic Con organizers need to plan better, but also said she was excited to attend.
"It made me kind of proud to be part of something that turned out to be that overwhelming explosion of geekiness," she said.
