Rather than just the disappointment, it is the confusion that I'm worried about. The adaption has a good chance of changing and omitting events, and this can lead to bad outcomes, especially among the impressions of anime-only viewers. You literally have two separate storylines in some cases and you could confuse the two plus you wouldn't really feel like rereading the source from the beginning unless you REALLY feel like getting the full effect and only hardcore fans do that, not general audience.

And yeah, very true, depends on the mangaka, but then again, I'm going on the basis that the mangaka/original author IS good. If the author sucks, well then, different matter.
