I'm a big fan of comic books but I would say my overall knowledge of the Marvel universe is below average for a comic book fan. I know a lot of origin stories but would like to be able to get into some of the great story lines for characters like Iron Man, Captain America, Hulk, Spider Man, Iron Fist, Luke Cage, Dr.Strange... Basically all of the well known characters.
I have a Marvel Unlimited subscription, but the amount of content seems overwhelming. I like reading the older comics (starting with things like tales of suspense) but for the most part enjoy crossovers, Deadpool (who I'm a lot more well read in), and some of the grittier story lines.
I guess my overall question is, do I have to start from the very beginning with every hero or are there parts that I can skip without missing out on the big picture? To someone who is well versed in marvel, what is the best order to read so as to not miss out on much but at the same time not have a list that would take me decades to read?
edit: I'm more looking for what comics are good to skip, there are great silver age comics but there are also ones that don't have any thing memorable and I would rather know which ones those are before reading them.
