OK, people. We’re well enough into the fall season to know what to watch and what not to watch.

While everyone has their favorites, as well as those they would like to see have a fast and furious death, this week is all about what you should be watching.

Hopefully some of you are already watching some of the shows on this list. If you’re not, then why not try something new? You just may find something you like.

1. “Doctor Who” - The coolest show on TV. Period. Some say “Lost.” Others say “Battlestar Galactica.” But no other show offers up the emotional smorgasbord that the Doctor does. David Tennant is doing a smashing job after taking over for the hugely popular Christopher Eccleston in the role of the Doctor. Billie Piper, meanwhile, continues to prove that her Rose Tyler is more than just a mere sidekick. The two have a cracking chemistry that says more than any kiss ever could. Not that fans would be opposed to such a thing. (8 p.m. Fridays on Sci-Fi)

2. “Heroes” - A living comic book as a weekly series? Never going to work, right? Think again. “Heroes” is the best new show this season. Its ensemble cast allows the characters to seamlessly exist in this fictional world within our own, with the standouts being Ali Larter as Niki Sanders, Hayden Panettiere as Clare Bennet (“Save the cheerleader. Save the world.”) and Jack Coleman as Clare’s dad, aka Horn-Rimmed Glasses. As the season progresses, it will be interesting to see how they all come together to battle the year’s big bad, the mysterious Sylar. (9 p.m. Mondays on NBC, encores 7 p.m. Fridays on Sci-Fi)

3. “Men in Trees” - While Anne Heche may not be leading lady material to some, she absolutely shines in this comedy as relationship expert Marin Frist, who decides to make a new life for herself in Elmo, Alaska, after discovering her fiancé is cheating on her with her best friend. The show has a “Northern Exposure” feel, with newcomer James Tupper steaming up screens as rugged outdoorsman/love interest Jack. However, the cutest couple title goes to the charming duo of Derek Richardson and Emily Bergl as Patrick and Annie, who are Marin’s No. 1 fans. (10 p.m. Thursdays beginning Nov. 30)

4. “Brothers and Sisters” - For a show that went through so many growing pains before it even hit the air, you’d never know it by watching an episode. A true family drama, the series continues to improve week-to-week and with a cast including Sally Field, Calista Flockhart and Rachel Griffiths, there’s no excuse as to why it shouldn’t. Whether it’s Kevin (a wonderful Matthew Rhys) trying to find his place as a gay man in a relationship or the tortured Justin (Dave Annable, who’s come a long way since last year’s “Reunion”) dealing with the psychic fallout from his tour in Iraq, the show offers a multi-dimensional look at the modern family. (10 p.m. Sundays on ABC)

5. “Veronica Mars” - Three seasons in and our favorite teen P.I. is still going strong, albeit now as a college co-ed. However some things never change, as the relationship between Veronica (Kristen Bell) and dad Keith (Enrico Colantoni, who continues to impress) is still the show’s driving force. Although we haven’t seen as much of Wallace (Percy Daggs III) and Mac (Tina Majorino), we still have Logan (Jason Dohring) and Sheriff Lamb (Michael Muhney) to keep us entertained. But seriously, how cute is Piz (Chris Lowell)? His crush on Veronica aside, his interaction with the rest of Veronica’s friends, especially his recent encounters with rape victim Parker (Julie Gonzalo), makes him a welcome addition to the Neptune crew. (9 p.m. Tuesdays on CW)

6. “The Office” - Now that Jim (the lovable John Krasinski) and Pam (the lovely Jenna Fischer) are reunited as officemates in Scranton, the show should soar to new heights. David Denman has brought new layers to Pam’s ex-fiancé, Roy; while newcomer Rashida Jones’ Karen adds another point in the tangled love rectangle (?) that this foursome creates. Also awesome is the fact that “Daily Show” alums Steve Carell and Ed Helms will be sharing the same office space. But Pam and Jim once again tag-teaming Dwight (Rainn Wilson)? Priceless. (8:30 p.m. Thursdays on NBC)

7. “The O.C.” - Who knew that the death of Marissa (Mischa Barton) would bring new life to the show in its fourth season? You can put your hands down. It was a rhetorical question. Sad sack Marissa was an albatross around the neck of this fan favorite, but her death may have come too late, ratingswise. Creatively, however, the show’s never been better. And as the mourning process comes to an end, “The O.C.” is poised to give fans its best season since year one. How can you not love a show that has its resident doctor (Summer’s dad) accepting a position at a certain hospital that “is famous for being wonderfully quirky. It’s called Seattle Grace”? Welcome back, O.C. (9 p.m. Thursdays on Fox)

8. “Nip/Tuck” - Speaking of being back on track, our favorite Miami plastic surgeons are enjoying a wonderfully deranged season. The show has gone back to its roots, focusing on Sean (a wonderful Dylan Walsh, who deserves more credit) and Christian (Julian McMahon, who continues to deliver a gleeful performance) and the rest of the McNamara/Troy clan. The effect that newborn Conor is having on Sean and Julia (Joely Richardson, whose presence will be missed) has been devastating, but has helped make the show must-see again. And the guest-star parade simply proves that “Will & Grace” got it wrong. (10 p.m. Tuesdays on FX, encores 11 p.m. Fridays and 10 p.m. Sundays)

9. “Bones” - While it’s no secret that Emily Deschanel and David Boreanaz are the main draw of this forensic drama, it’s the supporting cast of Michaela Conlin, TJ Thyne and Eric Millegan that keeps viewers coming back for more. The show may be under the radar, but the cast’s chemistry is anything but. The witty wordplay, whether it’s Brennan’s (Deschanel) pop culture cluelessness or the banter between almost any combination of characters, paired with the gang’s desire to piece together the week’s mystery - which almost always starts with the discovery of a skeleton in various stages of decay - helps craft one of the most humane and heartfelt forensic shows on TV. And it doesn’t slam you over the head with it, which also is a plus. (8 p.m. Wednesdays on Fox)

10. “Supernatural” - The Winchester brothers (Jensen Ackles and Jared Padalecki) may be mourning their dad, John (Jeffrey Dean Morgan), but that hasn’t stopped them from getting the job done. However, it has brought a new dimension to the pre-existing angst carried by Dean (Ackles) and Sam (Padalecki). The introduction of bar owner Ellen (Samantha Ferris) and her daughter, Jo (Alona Tal, who was Meg on “Veronica Mars”), this season has been a good thing for the boys and the show. In the end, though, it always comes down to Sam, Dean and the Impala. Ackles and Padalecki have made a great team even better this year. Now what, exactly, did John whisper in Dean’s ear just before the elder Winchester died? (9 p.m. Thursdays on CW)
