It is, but I suspect there are people who SO want to be excited that it doesn't matter if the product is crap : "I said I was going to be excited so I'll be excited, damn it!".
The alternative is too depressing: it means acknowledging more years of not getting anything worthwhile as MJ fans.
Looking forward to the excited posts next week, when CGOOTR is announced: "it'll be great to have this song on another, separate disc, as I only have it on one right now. This release will be the best ever! Now please announce For All Time as track 10!"
