When Avengers: Infinity War is released Friday, it will be the 19th film in the Marvel Cinematic Universe, which started back in 2008 with its debut film Iron Man. Since then, the MCU has made almost $15 billion at the box office and has for the most part been a critical success.

But have you ever tried to rank them from worst to best? Trust me, I underestimated how difficult a task that would be. I don’t hate any of these movies, so calling some of them the worst is a bit of an overstatement. Here are the MCU movies ranked from 18 to 1.

Iron Man 3 has moments of being OK, and I like director Shane Black. But there’s no way I’ll ever get on board with people’s love for this movie or the Mandarin twist. It’s a frustrating film in a once promising franchise. Speaking of …

Mickey Rourke doesn’t work for me, but there are certain scenes that do. Just not enough to get this movie out of the basement of this list. It’s a film that was rushed into production after the success of the first movie and it shows.

A forgotten MCU movie, The Incredible Hulk had the benefit of being compared to 2003’s Hulk and the disadvantage of coming out the same year as Iron Man. Even though Edward Norton is no longer the Hulk, Thunderbolt Ross is still played by William Hurt and made an appearance in Captain America: Civil War. There is also an after-credit scene where Tony Stark visits Ross at the end of The Incredible Hulk.

It only picks up when Thor and Loki interact, and ultimately bores the rest of the way through. Malekith is the most forgettable villain in the MCU and the lack of vibrant colors makes the movie dull.

This establishes Chris Evans as a strong choice to play Captain America, but doesn’t do enough to build the relationship between Steve Rogers and Bucky Barnes. This is a classic case of we had to get the origin story out of the way so we could make better movies in the future. To their credit, they did.

I enjoy everything about this movie except the plot. It’s very funny, but the plot. Damn, that plot for being essential to making a good movie.

There are scenes I love in this movie, but ultimately it was quite a letdown. It had obvious studio interference and tried to pack too much into a 2 hour-22 minute movie.

This is a solid origin film with a lot of laughs, great casting with Chris Hemsworth as Thor and Tom Hiddleston as Loki, who is still one of the MCU’s best villains. Kenneth Branagh excels in the director’s chair and the rainbow bridge was gorgeous the first time I saw it.

I really like this film. It sparked new life into the MCU with a different kind of hero capable of things characters in the universe are not accustomed to. Benedict Cumberbatch was born to play the role and Tilda Swinton is excellent as always.

Paul Rudd is the ideal casting for Ant-Man and add in Evangeline Lilly and Michael Douglas and you’re set. Despite Edgar Wright leaving the project, Peyton Reed stepped in nicely to direct a fun film.

This is the best Spider-Man with the best Spider-Man to ever put on the suit, Tom Holland, leading the way. The comedy keeps you laughing throughout, Captain America’s cameos are great and Michael Keaton’s Vulture is one of the MCU’s top villains.

This movie is so much fun. Probably the most entertaining of the MCU films. It has flaws, but the humor and action set pieces overshadow any of the negatives.

Throwing Chris Pratt into a MCU movie was one of the smartest things Marvel has ever done. Like Thor: Ragnarok, Guardians of the Galaxy thrives on its humor, but comes together as a movie a little better to give it the slight edge.

The MCU’s ability to bring all of its characters together for one film may be its crowning achievement and one the DC universe has tried to emulate. It’s no easy task, but Joss Whedon did it, making the MCU what it is today.

Speaking of crowning achievements, we don’t have any of this without Robert Downey Jr. as Iron Man. This movie kicked off the universe and was the character fans came out to see for a really long time while Captain America, Thor and Hulk got their footing. Us comic book movie fans will always be indebted to Iron Man.

This movie just came out a couple months ago, but the MCU once again managed to churn out a film that transcended the genre. Ryan Coogler is still batting 1.000 after directing three feature-length films and the acting talent is jaw-dropping.

The Russo brothers followed up their great Captain America sequel with a great Captain America sequel. Its two great action set pieces at the airport and with Captain America, Bucky and Iron Man fighting each other are arguably the best the MCU has to offer. And two different sequences at that as the airport battle relies on fun, while the end fight gives us an emotional struggle among characters who love each other.

This was the fully realized potential of what Captain America and the Marvel Cinematic Universe can be. Six years after the release of Iron Man, the Russo brothers finally figured out a way to make another great solo film. By making a realistic spy movie with superheroes in it, Captain America: The Winter Soldier provided a blueprint for how to make a good standalone superhero movie. Create a good story and weave superheroes into it. I truly believe that saved the Marvel Cinematic Universe and made it what it is today.
