As the Marvel Cinematic Universe gears up for its biggest event in years, fans are diving back into the archives—and one of the franchise's most controversial entries is getting a surprising second life on streaming. Iron Man 2, widely regarded as the weakest of Robert Downey Jr.'s solo Iron Man films, has climbed the Disney+ viewership charts ahead of Avengers: Doomsday, set to hit theaters in December 2026.

According to FlixPatrol, the domestic Disney+ top 10 this week is led by Spider-Man: No Way Home, but the list also includes Avengers: Age of Ultron—the most divisive Avengers movie to date—and, surprisingly, Iron Man 2. The sequel, released in 2010, has long been considered the black sheep of Downey's Iron Man trilogy, yet it's now drawing viewers eager to reconnect with the character before his highly anticipated return.

Not everyone loves westerns, but these films are so entertaining they might just convert you. Here are the best crowd-pleasing westerns ranked.

A Sequel That Expanded the MCU

Directed by Jon Favreau, Iron Man 2 arrived just two years after the groundbreaking original. While it didn't match the critical acclaim of its predecessor, the film played a crucial role in building the MCU's foundation. It introduced Scarlett Johansson's Natasha Romanoff (Black Widow) and marked the debut of Don Cheadle as James Rhodes, replacing Terrence Howard. The movie also set the stage for the first Avengers team-up, weaving in threads that would pay off in 2012.

Despite a mixed reception, Iron Man 2 grossed over $600 million worldwide on a $200 million budget. It holds a 72% "Certified Fresh" score on Rotten Tomatoes, with critics noting it "isn't quite the breath of fresh air that Iron Man was" but praising its performances and action. The film also featured standout turns from Sam Rockwell and Mickey Rourke as villains Justin Hammer and Ivan Vanko.

Why the Resurgence Now?

The timing of this streaming spike is no coincidence. With Avengers: Doomsday on the horizon—a film that brings back both Robert Downey Jr. and Chris Evans after their apparent exits in Avengers: Endgame—fans are revisiting the early days of the MCU. The movie is expected to be a massive undertaking, with a star-studded cast and a budget that reportedly rivals any previous Marvel production. Disney is banking on Doomsday to reignite interest in the franchise, which has faced challenges in recent years.

This trend mirrors other streaming surges seen across platforms. For instance, Avengers: Age of Ultron finds new life on Disney+ ahead of Doomsday, while Angelina Jolie's Maleficent casts a spell on Disney+ streaming charts ahead of 2026. Even Brendan Fraser's The Mummy: Tomb of the Dragon Emperor surges on HBO Max ahead of a 2026 sequel, showing that audiences are hungry for nostalgia as new installments approach.

What's Next for Iron Man Fans?

Downey's return as Tony Stark in Avengers: Doomsday remains one of the most talked-about plot points in the MCU. While details are scarce, the film is expected to explore multiversal consequences and potentially tie into the events of Spider-Man: No Way Home. For now, fans can stream Iron Man 2 on Disney+ and see how the seeds of the MCU's future were planted—even in its most criticized chapter.

As the countdown to Doomsday continues, expect more classic MCU titles to climb the streaming charts. Whether you love it or hate it, Iron Man 2 is proving that even the weakest link in a franchise can find new life when the stakes are this high.
