Personally, I'm pretty open on storytelling. I just want diversity to it. When everything is 6 issue stories I hate it. When everything is year-long arcs I hate it even more. When everything is done-in-one's I get bored.
Mix it all up so that sometimes it's nice simple reading and other times it's amazing impactful stories and that's how I like it. And if a plot is going to be more than 4 issues it better be freaking important and amazing because if it isn't I get more bored than the done-in-one's.
A good example of this was the early-mid 90's Amazing Spider-Man run. You had a two issue run with Doom, then a 3 issue run with Nova and the Tri-Sentinel, then a 6 issue event of Round Robin: The Sidekick's Revenge, then a 2 part Cardiac story, then a 3 issue introduction to Carnage with Venom, then a single issue with Shocker, a single issue with Lizard, and it went on and one with smaller stories but it all flowed and connected instead of being just solo stories. That layout's what got me into comics.
