the hulkbuster from avengers: age of ultronMarvel fans, rejoice: "Avengers: Age of Ultron" is finally here! I don't know about you, but I've been ready for the sequel to "The Avengers" for three years. There's a good chance that the entire American population will go see "Age of Ultron" when it premieres this Friday, May 1st. But just in case you're one of the few still looking for a reason to go watch one of the most anticipated movies of the year, here are five:

1. The World's Coolest Team Is Finally Reunited
We had already grown to love Earth's mightiest heroes because of their appearances in the movies that came before "The Avengers." But that 2012 blockbuster showed us what it was like to have the team be united, when they work together to fight bad guys and say some fabulous one-liners. In the films that came after "The Avengers," audiences got to see even more development of our favorite characters. It will be great to see the team back together after all of these changes. Will they still be able to work together when they're facing new challenges and new characters? Speaking of which...

2. Fun New Characters
"Age of Ultron" is going to introduce a whole host of new and exciting characters. Scarlet Witch and Quicksilver have appeared prominently in trailers. These characters are twins who appear to be working with big bad guy Ultron at first, but may switch their allegiances later on. We'll also be seeing mysterious new character The Vision. Not much is known about him yet, other than he is played by Paul Bettany, who voiced Tony Stark's AI butler, Jarvis. It will be interesting to see how these new players fit into the Marvel Cinematic Universe, and whether they will affect our favorite characters for better or worse.

3. James Spader as Ultron
Ultron is a new character, but he's so important that he deserves he's reason enough to see the movie. James Spader is a fabulous actor, and if the trailers are anything to go by, he will be playing Ultron with an enticing mix of terror and charisma. Created by Tony Stark, Ultron is a robot with artificial intelligence and a mind of his own, Frankenstein's monster for the digital age. I'm excited to see just exactly how this villain will upend the Avengers, and how James Spader will portray such an iconic character.

4. Awesome Action Scenes
Come on, it's a Marvel superhero movie. There are going to be some fabulous action scenes, delightful fights, and mayhem included. Of course, audiences are coming for the story as well as the explosions, but beautifully executed action sequences don't hurt.

5. Great Dialogue
One of the reasons that "The Avengers"is so special is its dialogue. It's a superhero film, but there are some truly clever moments in terms of one-liners and witticisms given by characters. If "Avengers: Age of Ultron"can live up to its predecessor in terms of dialogue as well as in terms of action and character development, it will be a great movie indeed.
