“The Kids Are Alright” Season 1 is ending tonight, and the season finale will have to serve as a series finale. ABC decided to cancel the freshman comedy series.

Creator Tim Doyle announced the cancellation. He took to Twitter to announce the sad news earlier this month.

Fans are already making an effort to save the show with the hashtag #SaveTheKidsAreAlright. A petition was launched and has amassed over 6,000 signatures. The campaign’s message is simple. “Sign this to show ABC we want The Kids Are Alright reinstated/renewed,” the description reads.

The revival effort even got support from Luke Skywalker actor Mark Hamill. The Star Wars alum was part of the very successful campaign to bring back “Brooklyn Nine-Nine” last year.

Unfortunately, “The Kids Are Alright” ratings were a problem. It only pulled in 4.14 million viewers and 0.87 in the coveted 18-49 demographic, according to TV Series Finale. That placed it smack in the middle of ABC’s overall ratings. Shows with lower ratings, like “Fresh Off The Boat” and “black-ish,” were renewed, but they’re also more established. They have syndication deals that might make it worth it for ABC to renew the veteran comedies.

The price of the period show may have been a factor. “The Kids Are Alright” focuses on an Irish-Catholic family living in 1970s California.

ABC cut quite a few TV shows this month, which is typical for broadcasts networks in May. In addition to “The Kids Are Alright,” the alphabet net also canceled comedies “Splitting Up Together” and “Speechless.” Canceled dramas include “Whiskey Cavalier,” “For the People” and “The Fix.”

The series finale of “The Kids Are Alright” airs Tuesday at 8:30 p.m. EDT.
