When you haven’t read the comics.(r/Marvel)
Don’t worry about being behind. Nobody has read everything, and everybody starts somewhere. I only started getting into comics about five years ago myself. It’s all about taking it easy and just reading good stories.
If you want to get into Marvel, here’s some good recent-ish stuff I recommend checking out:
- Iron Man by Matt Fraction vol. 1: The Five Nightmares
- Captain America by Ed Brubaker vol. 1: The Winter Soldier
- Thor: God of Thunder by Jason Aaron vol. 1: The God Butcher
- Indestructible Hulk by Mark Waid vol. 1: Agent of SHIELD
- Hawkeye by Matt Fraction vol. 1: My Life as a Weapon
- Black Widow by Nathan Edmondson vol. 1: The Finely Woven Thread
- Avengers by Kurt Busiek vol. 1
Any one of these is a good place to start with the Marvel Universe. I would recommend checking your local library first, they may have a lot of these available to check out. I’d also want to let you know that Marvel has a digital subscription service called Marvel Unlimited which has every comic I just mentioned available to read for just $10/month or $70/year. It’s a real good deal.
