Those of you who love Joss Whedon, and have not had the chance to watch Firefly yet, here's your chance to watch it free online.
Also, there are many other shows available via IMDB now.
edit: It appears this isn't the pilot episode, which is about 2 hours long. I'm not sure if the pilot is on IMDB, looking for it now.
edit#2: http://www.imdb.com/video/hulu/vi3900702745 <-- Episode 1 Pilot, watch this first, then follow with Episode 1 through 10, skip 11, then finish out the rest.
Enjoy!
