As “Thor Ragnarok” hits theaters this weekend (likely generating a massive box office take in the process), now’s as good a time as any to look back at the Marvel Cinematic Universe as a whole.

There was the one that started it all, “Iron Man,” which launched the MCU in 2008. Robert Downey Jr. defined — and continues to, in the Avengers movies — the snarky Tony Stark as it went on to spawn two sequels and break box office records.

And then, of course, there’s Thor, everyone’s favorite God of Thunder, with Chris Hemsworth headlining movies ahead of “Ragnarok” in 2011 and 2013. Speaking of the Hollywood Chrises: Chris Evans made his debut as Captain America in his own movie ahead of the release of “The Avengers,” which started its own series.

“Guardians of the Galaxy” added a new flavor to the movie universe in 2014, with Star-Lord, Gamora, Rocket, Groot, and Drax capturing the hearts of fans and starting its very own series within the MCU.

Which Marvel series is your favorite? Weigh in below! (Note: This poll does not include movies that didn’t spawn a sequel, like “The Incredible Hulk,” or movies that haven’t seen their sequels debut yet, like “Ant-Man,” “Doctor Strange,” and “Spider-Man: Homecoming.”)
