Watch these before they disappear...
Primeval - BBC America
Interesting concept, holes in time and dinosaurs. A recent episode had a dinosaur walk in to England around the middle ages, then had both come to the present. Well acted and Hannah Spearritt is hot. I just read that this is the final season. pheh.
Eureka - SyFy. Most should know this show already. Light hearted and funny. Well acted and a good chemistry. Plus they teased the leads lovelife and then eliminated his whole future with her from the timestream. Really good show.
Leverage - TNT
I really love this show. A must watch.
In Plain Sight - USA
Probably the best show USA has to offer, and that's saying a lot with Royal Pains and Burn Notice. All three are worth a look.
Life After People - Discovery
Weekly series based on the documentary they ran a year or so ago. Kinda cool, but a tad creepy.
