There's a neat site:
http://www.tvrage.com -- handy for digging up info on New series, Old ones, and their Seasons/Episode lists, plus when new seasons if any of a show you liked will be coming out.
Plus, of course,
http://www.imdb.com/Seems I'm a bit of an old
"Square eyes".

I noticed
'The Game of Thrones' is having a new season in 2013.
I've watched and loved the Joss Wheddon Written and Directed
"Firefly", and the Movie
"Serenity".
http://www.tvrage.com/Firefly -- There was some problem with deciding in what order to show the episodes, plus I've seen a 'Reunion - 10th anniversary show' was released recently.
I sat through
'The Wire' which was, "Set in Baltimore, this show centers around the city's inner-city drug scene."
http://www.tvrage.com/The_Wire -- There are characters from that show popping up in heaps of other shows I note, great cast. Story was pretty grim, which the reality is too.
Have tried to watch
"The good wife", but haven't got my head around the Title.

Two shows:
I've enjoyed which haven't been mentioned are
'Eureka', ScyFi series about a Government run Science community that invent something which threatens to destroy the fabric of something or other each episode. A bit 'Disney', but I thoroughly enjoyed the seasons, due to the actors and plot development.
Same goes with
'Warehouse 13', which can be dorky, but great concept. "Artifacts" that trigger dangerous actions are stored over milleniums which have to be collected, or retrieved. Like 'Sherlok Holmes pipe', if in the wrong hands is dangerous, ...

Also,
"Haven" (Based on a Stephen King story:
http://www.tvrage.com/HavenIt takes a village to hide a secret...
Deep in the heart of Maine, Haven is a town where people with supernatural abilities have migrated for generations because it mutes their powers, allowing them to lead normal lives. At least, until recently. When hot-shot FBI agent Audrey Parker is called to Haven to solve the murder of a local ex-con, she catches the killer but uncovers a much deeper mystery about this town. Each week, as the town-peoples’ dormant powers begin to express themselves, Audrey will try to keep these supernatural forces at bay while unraveling the many mysteries of Haven – including one surrounding her own surprising past in this extraordinary place. If you haven't seen
"Dollhouse", I loved it. --
http://www.tvrage.com/Dollhouse
People 'sell' their lives, have their minds wiped and have pre-packaged ones programmed in for wealthy clients who need someone 'Special'. The show goes a lot deeper than first expected, not knowing who is running the organisation, or how big it is.
"Echo (Eliza Dushku) is a young woman who literally embodies the Army's slogan "Be All You Can Be". She is one of a group of men and women who can be, literally, anyone or fulfill any role -- by getting imprinted with personality packages, including memories, skills, language—even muscle memory—for different assignments. The imprints can take them from role to role -- from super spy to kidnap negotiator, from fun weekend fling to expert bank robber, from devoted lover to earth-mother. When not imprinted with a personality package, Echo and the others are basically mind-wiped, living like uncomplicated, unquestioning children in a futuristic dorm/lab dubbed the Dollhouse, with no memory of their work outside the house—or of much else.
The show revolves around the childlike Echo's burgeoning self-awareness, and her varying ability to recall who she was before, a problem that begins to seep into her various imprinted personalities and puts her in danger both in the field and in the closely monitored confines of the Dollhouse.
