The air may be getting crisp, but the TV calendar is heating up. As a streaming editor who watches TV for a living, I’ve rounded up the biggest new and returning shows to watch across Netflix, Paramount+, Prime Video and more of the best streaming services.

This week brings a fresh take on Stephen King’s “Carrie,” a swashbuckling new adaptation of “Treasure Island” and “Below,” a spooky seaside thriller. There’s also a new “NCIS” spinoff that takes the franchise to New York, because apparently there are still corners of America that haven’t been investigated by federal agents.

With October bringing cooler weather, there's a particularly good excuse to stay inside with the TV remote. Here’s what to watch this week.
