I wish they'd do a Librarian TV _series_
Even if they couldn't do a regular, full year of shows, it would be nice to get at least 13-episode seasons . . . maybe running every other week (on a weekend, maybe) or half a year, maybe. Although only as long as it's still Noah Wyle, Bob Newhart and Jane Curtain.
I've liked all three films quite a bit (giving them all 8/10). The films already have a series feel, imo, and they have a great premise for easily producing a large number of plots. They could also do episodes that focus more on Bob Newhart or Jane Curtain's characters, and give Jane Curtain's character a more interesting backstory for that.
