Snap judgments on the fall season

OK so it’s based on trailers, but here goes

Another fall, another crop of lawyers, doctors and sitcom families fighting for your attention.

The broadcast networks presented their new fall shows at their annual presentations to advertisers, and now trailers are available.

In fairness, we can’t really evaluate a TV series based on a quick trailer, but we can tell a few things: Does the cast have instant chemistry? Is the concept novel, or tired? Here are quick assessments of the fall shows based on early peeks at new fall series.

ABC

A Million Little Things This This Is Us copycat follows a group in their 30s reeling from the sui- cide of a friend. The trailer is all tragedy and drama with no levity. I’m wary of the darkness. The Rookie

Never count out the allure of Nathan Fillion. The Rookie feels like a standard procedural with a new hook. Fillion stars as a middle-aged divorcee who decides to join the LAPD.

CW

Charmed It’s tough to accept three new women replacing the Halliwell sisters in the reboot of the late 90s/early 2000s supernatural series. The trailer hits the important notes from the original – sisterhood, the three basic witch powers, a spooky mansion and a demon – but I’m not sold yet.

Fox

Rel

Get Out breakout star Lil Rel Howery plays Rel, a recently divorced man struggling to carve out his new identity in Chicago’s South Side. Howery is so appealing that the trailer seems fresh.

NBC

I Feel Bad

Produced by Amy Poehler and inspired by Orli Auslander’s book I Feel Bad: All Day. Every Day. About Everything, the family sitcom shows a mom (Sarayu Blue) as she struggles with her kids, her husband, her own parents and her job. The trailer doesn’t have many laughs, but it’s an interesting spin on the formula.
