It's a delicate balance, but at least for me, too much (or the wrong kind) of vagueness is actually a significant turn-off. As a comparison, if someone summarized their story as "Stuff happens. But it's exciting stuff!", would that entice you?
Now, it wouldn't surprise me in the least to find that I'm more sensitive to that kind of thing than the average person, but that's my take.
Also, the wording in the last version feels a bit clunky, although I'm not managing to come up with any specific suggestions for smoothing it.
