Smash: Glee for Adults?

Smash has been commonly linked with Fox's Glee as they are both of the musical genre. This article in the Hollywood Reporter briefly discusses those comparisons and to a certain extent even accepts them, if Glee is for teens (not exclusively) then Smash is most certainly for an older demographic (also not exclusiveluy).

Also this article discusses the differences in the subject matter from the original inception of the series, as it now is NBC's big hit and does not belong to Showtime. Had the show stayed with Showtime it would most certainly have catered to an adult audience and have much less in common with Glee and its "high school musical" nature. Personally, as a fan of Glee (although my loyalty has considerably faded) I understand the comparisons but I stress to friends that Smash is not Glee, and the only thing in my mind that they have in common is the musical aspect. What do you all, those who have watched both shows, think about the comparisons?
