Hello! I've been collecting comics for about half a year now, but they just seem to gather dust on my shelves once I take a glimpse at them. When subscribing to a superhero series, I tend to be interested in the first couple issues, then back off once the story becomes bland or too dialogue heavy. In my experience, the most action-packed and best written issues stem from important story arcs (EG: Fear Itself), and I think I'd save money and become more interested in the 'cream of the crop' of comics by only collecting those issues.
My question is how to go about collecting a story arc in it's entirety, take Fear Itself for example.
Comicvine (http://www.comicvine.com/fear-itself/39-56288/) lists Fear Itself as having 154 issues, but I don't really understand how/why there are comics related to Fear Itself, without the giant title 'Fear Itself' on the cover (EG Iron Man, Avengers Academy). Anyone have some good tips? Sites for checklists? Other good arcs to collect?
