It is weird logic. If you buy an issue, don't like it, and then say so, the creators can say "We didn't force you to buy it!" They can even say, "Don't worry, the next few issues will be better." If someone buys the first issue of SECRET INVASION and doesn't like it, but is told to be patient, eventually buys the whole series and still doesn't like it, the creators can say "Well, why did you keep buying it if you didn't like it?"
