I have never read comic books until the last month in which I read the Invincible Series(by Robert Kirkman) because I wasn't patient enough to wait for the show lol. After that, I've read a few more Graphic Novels, and now I'll try venturing in the marvel comics, but there are so many, and I don't know how to start, what to read, what not to read, order of reading, idk, I just really need some help. I'm in the final stretch of the The Walking Dead Series, and would love to, after finishing it, dive right the way into the marvel comics.
At this point, anywhere. Once you get to a point that things are being referenced that you haven't read, then you go back and find the referenced issue.
You also might want to specifically search for a series that had a limited arc so there's a finite amount of issues to read through.
And if you don't care about "cannon", I remember loving the "What If?" and "What The--!?" series. Very much has the vibes of kids talking about "What if the Wolverine was also The Hulk" ...
