I've always enjoyed the Terminator movies, along with the former series, TSCC.
Though it's never returned to the perfection of its first season, I still continue to follow Heroes, hoping that one day, it'll return to its roots. (And ditch Gretchen.)
Chuck! My latest interest, and one that always delivers a genuine laugh for me with each episode.
Futurama is hysterical, hands down the best cartoon-comedy ever created! If you don't agree you can take Bender's catchphrase and refer it to yourself. It's also returning to television after several years off the air.
Since it's cancellation, Firefly has become a cult classic, spawning the feature film Serenity and a hilarious Nathan Fillion Halloween spoof.
