That kind of thinking is what both DC and Marvel count on, unfortunately. Glad to know you're starting to kick the habit.
Hell, it's what movie studios, television networks, etc. count on, too!
While I've never been one to buy something I do not enjoy, I do dislike dropping books in the middle of a storyline. That and the promise of a new creative team are my kryptonite. I bought
Teen Titans for well over a year, despite not really enjoying it, because every time I decided I was going to drop it, I heard a new creative team was coming on and I stayed, hopeful that it would get better.
What gets me are the people who buy a book they know they hate. I don't understand spending my money on something I hate, even if I derive enjoyment over hating it. Case in point,
Countdown, which I dropped early on. Others continued and spent over a $100 on something they claimed to hate. Between the various sites which post scans and the websites which slammed it in the reviews, I got all of the enjoyment I needed to out of hating it for free (minus the 7 or so issues I bought at the beginning).
