The best new show of the fall — with nearly no publicity — begins tonight on a streaming service. “Reboot” (Hulu, streaming) is a  sharp new comedy from the co-creator of “Modern Family” Steven Levitan with a dream cast that includes Keegan-Michael Key, Judy Greer as stars of a 20-year-old sitcom coming back to do an edgier version of it by an indie talent (Rachel Bloom of “My Ex-Girlfriend”). Trouble is that the old school show originator (Paul Reiser) is also on board. 

The inside-the-industry jokes mix easily with broader humor and a dash of sentiment. It’s a fun new show with a lot of smart commentary on where TV is going. Three episodes are available today; the rest of the eight-episode season will come on subsequent Tuesdays.

People say the FBI is out of control, and that’s certainly true in terms of TV shows, with all three of the Dick Wolf franchises “FBI” (CBS, 8 p.m.), “FBI International” (CBS, 9 p.m.) and “FBI: Most Wanted” (CBS, 10 p.m.) returning on the same night; the first for its fifth season, the second for its second, the third for its fourth. 

There are also season premieres for a couple of network hospital dramas, “The Resident” (Fox, 8 p.m.), back for its sixth season, and “New Amsterdam” (NBC, 10 p.m.), back for its fifth and final season. 

“The Bachelorette” (ABC, 8 p.m.) comes to an end with at least one of the two bachelorettes still around to make a decision. But is it a law that there must be an engagement at the show’s end? It will be excruciating enough by clocking in at three hours.

His fourth stand up comedy special for the streaming service, “Patton Oswalt: We All Scream” (Netflix, streaming), was shot in Denver.
