Eureka
SciFi channel original
Wacky hijinks ensue. It's an amazing show
+ 1 billion for Burn Notice. It's my
favorite show.
Warehouse 13
SciFi original
Wacky hijinks ensue, and a surprising amount of compelling drama, too.
Alphas
SciFi original
If you like Heroes, you'll probably enjoy Alphas. It's like a cheesier version of Heroes.
Royal Pains
Medical drama
If you like House, you'll probably enjoy Royal Pains. Concierge doctor with even better diagnostic skills than House, but none of the blind hatred for humanity.
Leverage
Crime drama
Bad guys doing good things in amazing ways. Every episode is a 30 Xanatos Pileup.
Rizzoli & Isles
Police drama
Humor, drama, and a pretty respectable cast (also, holy FUCK I'm in lust with Sasha Alexander). If you like police procedurals at all, you'll definitely enjoy this one.
Suits
Legal drama
Witty banter, and excellent stories. Can't recommend it highly enough.
Castle
Police procedural
It's got Nathan Fillion in the lead role. 'Nuff said.
The Mentalist
Police procedural
Like House, only with the CBI (California Bureau of Investigation)
Franklin & Bash
Legal drama
Hilariously funny, and I hope it's been renewed for a second season!
Iron Man (the anime series)
It's fucking IRON MAN
It's fucking IRON MAN
Top Gear (US)
Auto show
Funny hosts, silly challenges, awesome cars - what's NOT to love?
Curb Your Enthusiasm
HBO Comedy
It's smart, witty humor. Check youtube for "Larry David"
Dexter
Crime drama
Serial killer hunting bad guys. It's a shame that Michael C Hall is being such a dick in contract negotiations for next season. He wants $24 million for next season (and seasons following), but Showtime is digging in their heels at $20 million. Fucker! It's a RECESSION, be happy with your 20 mil. Jesus.
Mythbusters
It's mythbusters!
Jaime want big boom! (i.e.: shit blows up. A lot)
Bones
Police drama (ish)
Forensic anthropology made interesting. Also, David Boreanaz(sp?) and Emily Deschanel.
Death Valley
Comedy
It's like Reno 911, only with zombies, vampires, and werewolves. Hilarious.
+ 1 billion for Big Bang Theory
Prime Suspect
Police procedural
It's just getting started, but it's got a
LOT of promise.
Terra Nova
Sci-fi
It's a shame this show probably isn't going to get renewed for a second season, it's been pretty stellar so far.
Criminal Minds
Police procedural
I love it, but it gets pretty formulaic at times and suffers from the "CSI Complex" - where people do jobs that they aren't supposed to do in real life.
NCIS
Police procedural
Gibbs is a genius, Ziva is a badass, McGee is geeky, DiNozzo is an hilarious example of peter pan syndrome. All in all, it's excellent.
Hawaii Five-O
Police procedural
It's a good remake of the original
Charlie's Angels
Dude, if you don't know what Charlie's Angels is, you need to get out more
I really only watch this for the hot chicks. Lots of T&A.
Penn & Teller Tell a Lie
Uhh... P&T?
It's Penn & Teller. They may be assholes off-stage, but their shows are always worth watching.
Person of Interest
Sci-fi police drama (ish)
It's interesting so far. Sort of the same premise as that one Tom Cruise movie, but without the precognitive bullshit. Also, not set in the future.
How to be a Gentleman
Comedy
So far, it's pretty good.
Homeland
Spy drama
Tits & ass, and believable spy drama. I'm liking it so far.
Last Man Standing
Comedy (not premiered yet)
Tim Allen returns to television! *grunt grunt grunt*
White Collar
Crime drama
Matthew Bomer makes an AMAZING con artist, and the guy who plays Peter Burke is amazing as his FBI "handler". Also, Tiffany Amber Thiessen (who I've had a crush on for the last 20+ years).
Covert Affairs
Spy drama
Piper Perabo plays an excellent (and hot) spy. Did I mention that she's hot?
Human Target
Action
GOD I loved the ever-living SHIT out of this show. Sadly, it didn't make it past season 2

. Fuck you, Fox, and your insistence that anything not a reality show is shitty!
There's more, but I can't remember it right off-hand. Take your pick, and holy shit I watch a lot of crime and legal shows!
