This thread popped up when I was looking to get into reading some comics. I am considering signing up for Marvel Unlimited. I am pretty sure I have at least three series I would be interested to start reading. From there, it would likely spiral to more.
Take it from a lifelong comic fan, unless you are a collector, who loves the hunt more than the story, do not do single issues.
By trade paperbacks (TPB). They will bundle the relevant stuff together in one book. Let me explain the main issue:
See, comic books are like the worst TV schedule in history. Once a month, two weeks if you're lucky, you get a snippet of the story for that character/team. If you're lucky the storyline is concluded in six months to a year.
But, that isn't everything. You are reading and it makes a reference to something you haven't read with a *'next to it. In a small notes box there is a message telling you that happened in issue# 127-128 of some other series you don't read. If you are really into the story then you have to find those issues, which are months old and require you going to a comic store and digging through the bins. And if it is an epic tale it is in multiple series. Death of Superman takes place in nearly every a Justice League related series out there. When Doomsday wasn't fighting Superman someone else was fighting him. If you want to understand Doomsday as more than a random destructive creature you have to read a lot. And the return of Superman? First you had four new comics to read for like a year, if you wanted to keep up. They were all important because Lois is trying to hunt down why these four new Superman-like heroes showed up just as Superman died. Then the actual return. Well that rocks the entire DC universe, more series, five of which are telling the main story.
And Death of Superman is one example. Marvel is no better. Christ, anytime something threatens mutants every X-team is affected in both solo and team efforts. Do you know how many mutant gene characters there are? And then Civil War. Every Marvel character that lives in America was fighting each other. The main storyline was epic by itself, but then you get every major character or team with their own side story.
Oh, and then there is the occasional lull between big stories. Or worse yet, a crappy phase where it feels like the main writer must have had a stroke. Then you lose interest.
With TPBs you get the relevant stuff and side stories can be bought in their own TPB. If it is a noteworthy event, it is in a TPB. And you aren't spending money on issues that are horrible.
I can't remember when I gave up the collecting and subscribing. It was either Death of Superman or Executioner's Song. I said screw it and walked away.
And now you can get TPBs digitally. You can get a six-issue storyline for $9.99. Compare that to $3-$4 an issue. And if you are lucky you can get a compendium, with like 36 issues in it. That's how I've been reading Walking Dead.
