Well, awards certainly don't mean everything, but LOST did win last year's Emmy for Best Drama, this year's Golden Globe for Best Drama, and was Show of the Year for the National Association of TV Critics last season. Industry professionals certainly seem to like it, and it was among the Top Ten most popular series in the ratings last year and so far this year, so the general public seems to like it, too.
So, there is support for it out there as well as with a few of us at HHW.
