What Is NCIS About?
NCIS follows a team of special agents who investigate crimes related to Navy and Marine Corps personnel no matter what the rank or position, from murder and espionage to terrorism and stolen submarines. And that's the whole point.
The show was created by Don McGill and Donald P. Bellisario. Genres: Crime, Drama, Action & Adventure. But really, it's a comfort show with a badge. Usually an episode gives you a case, a couple of good lines, and some good team chemistry.
Here's what I think sustains it. You could watch any episode in any order thanks to the case of the week. However, the characters' long-standing relationships (the teasing, the loyalty, the grief when they lose someone) pay off for the viewers who follow the show every week.
Is NCIS Worth Starting in 2026?
Yes, if you enjoy procedurals that are full of heart. It's not prestige TV and it's not trying to be. Don't expect big serialized plot twists like you might get in a streaming series.
But consider an evening where you want to watch something at a comfortable pace that is also familiar. NCIS delivers that, and there's a ton of it, with 24 seasons available (see the Wikipedia season 24 page). I'd start with a modern-era episode and go back in time if you get hooked.
Here's a simple way to evaluate it: watch two or three individual cases back to back. You'll get a good sense in no time whether the banter, team loyalty and methodical pacing work for you, and you won't need a refresher to understand it all.
Who Stars in NCIS Season 24?
The Season 24 cast includes Sean Murray as Timothy McGee, Wilmer Valderrama as Nick Torres, Katrina Law as Jessica Knight, Brian Dietzen as Jimmy Palmer, Diona Reasonover as Kasie Hines, and Gary Cole as Alden Parker. Michael Weatherly is also credited in the cast as Anthony DiNozzo, the character fans associate with the show's earlier years.
| Actor | Character |
|---|---|
| Sean Murray | Timothy McGee |
| Wilmer Valderrama | Nick Torres |
| Katrina Law | Jessica Knight |
| Brian Dietzen | Jimmy Palmer |
| Diona Reasonover | Kasie Hines |
| Gary Cole | Alden Parker |
| Michael Weatherly | Anthony DiNozzo |
See, a cast this big across this many seasons tells you something. Characters like McGee have been anchors for years, and newer faces have had time to settle in.
Gary Cole as Alden Parker
Gary Cole plays Alden Parker, and honestly, the difference in the team energy is remarkable with him at the helm now versus in previous eras. He's a lot drier, more measured. Some longtime viewers miss the old dynamic; I understand. But this team still clicks.
Wilmer Valderrama and Katrina Law
Valderrama's Torres and Law's Knight bring some of the more lively scenes to the show. If you like back-and-forth in your investigations, those are your guys.
What Happens in Season 24?
Season 24 is now on the air, with the latest episode having aired on October 6, 2026, while episode 2 is set for October 13, 2026. The show maintains the standard format, which includes a new case to solve and a ticking clock, with a team that works best when it's under pressure.
I won't pretend to spoil what I haven't confirmed. What I do know is what you might expect from this series: cases that involve Navy and Marine Corps personnel and everything from espionage to terrorism. That "Back in force" tagline is well-deserved, by the way. It hints at a team pulling together, and that's what the best episodes of NCIS do (see the TV Guide season 24 article).
When Does Episode 2 Air?
Episode 2 of Season 24 airs on October 13, 2026. If you're tuning in to watch live, that's the next date to circle. You can always hold off and stream the season as it builds up. Here's a practical angle most guides skip.
With the show on multiple platforms (more on this below), you can usually catch up on earlier seasons while new episodes air weekly, so you'll never be left waiting between drops.
Where to Watch NCIS
You can stream NCIS on Netflix, Hulu, fuboTV, and Paramount+ Premium. Availability can vary by region and by season, so always double-check which seasons of the show are included before signing up.
| Platform | Good to know |
|---|---|
| Netflix | Handy for catching up on earlier seasons |
| Hulu | Good for ongoing viewing |
| fuboTV | Live TV option for watching as episodes air |
| Paramount+ Premium | A natural home for the franchise |
I won't quote subscription prices, because those change and you'll want the latest number. Head to each service's website for with-ads and without-ads tiers and current pricing.
If you want to watch Season 24 live as it airs, fuboTV is the live-TV route. If a deep catch-up on the back catalog is your goal, an on-demand service is the smarter choice.
Why NCIS Has Lasted Since 2003
NCIS has lasted because it pairs a dependable case format with characters people genuinely care about. It premiered September 23, 2003, and that staying power is rare in network TV.
Think about it. Plenty of procedurals fade once the novelty wears off. This one kept refreshing its cast while holding onto what viewers loved. Sound familiar? It's the same trick long-running comfort shows use.

If You Liked NCIS, Try This
If this formula clicks for you, plenty of other crime procedurals with large ensembles will satisfy that craving. Look for shows that center on a cohesive team, one case per episode, and a dash of workplace comedy. That's the sweet spot.
My honest opinion? To me, it doesn't feel like NCIS is trying to be original. It's trying to be dependable, and after twenty-four seasons, being dependable is an accomplishment. Not a lot of shows get to say that.
