SEASON PREMIERE: Last year, this long-dormant sitcom returned to TV along with another long-dormant former hit sitcom, ABC’s Roseanne. That series is returning this season, but under a new name and without its former star, whose tweets and other behavior led to her dismissal from her own show. The stars of Will & Grace engaged in no such extracurricular controversies – and, thus, return for Season 2 tonight without incident, and with a new roster of guest stars lined up for year two of this reboot. That starts, with tonight’s season premiere, with the first of a recurring series of guest appearances by former Friends star David Schwimmer.
