Just because the conversation recently got me thinking, here's how I rank superhero movies I've seen:
The Top Shelf: Dark Knight, Winter Soldier
Excellent: Spider-Man 1&2, Iron Man, Batman & Batman Returns, X-Men First Class & Days of Future Past & X2, Avengers, Guardians of Galaxy
Great: Superman 1&2, Batman Begins, X-Men, Deadpool, Iron Man 3
Good: Captain America, Hulk & Incredible Hulk, Daredevil, Batman Forever, Thor, Wolverine, Avengers 2, Ant-Man
Average: Dark Knight Rises, Amazing Spiderman, Iron Man 2
Below Average: Thor 2, Man of Steel, Spiderman 3, Fantastic Four Silver Surfer
Trash: Amazing Spiderman 2, Superman Returns, X-Men Origins & Last Stand, Batman and Robin, Elecktra, Catwoman, Fantastic Four
Those are all the ones I can remember well enough to rank.
