Good series

The walking dead?

Actually, can't guess.

Red Dwarf. One of only 2 TV series I've watched this year. The other being A Bit of Fry and Laurie.

Depends on what kind of shows you like to watch.

Fringe has a fifth season. Actually, there's some chapters in season 4 that wouldn't make any sense if there weren't a fifth one.

Primeval / Primeval: New World / Doctor Who / Stargate SG-1
And as I said above, finish watching Fringe.

Family Guy has some funny stuff in it, if you're into adult comedy.

Supernatural / Dexter / Braking Bad.

Stargate is still after 16 years my favourite series, though Game of Thrones is very serious competition.
Other than that: Breaking Bad, Continuum, Downton Abbey (Superb series), Doctor Who (The 2005 reboot), Falling Skies, Person of Interest, Elementary, Sherlock

And I'm sure I could give you more names, but these are the best I've seen.

Watch The Walking Dead, you won't regret it ;) best series I have ever watched!

Since other good series I wanted to say have already been written, I'll throw in Falling Skies. :)

Here are a few series which I found entertaining:

1) Burn Notice
2) Justified
3) NCIS

If you're into "older stuff," try the "I Love Lucy Show" for comedy.

• The Walking Dead
• Game of Thrones
• Spartacus

Battlestar Galactica, but don't blame me when you end up missing work/school because of it.

Edit: Oh, and my gf has got me into the BBC Sherlock Holmes-- definitely worth checking out!
