$100 is a lot of money to drop if you're not sure you'd even like the show. I would absolutely download the first season (or borrow it from a friend, if possible), and if it was worth my hard-earned money, I'd go ahead and buy the entire series. I'm sure we've ALL downloaded movies/music/TV shows, and AFAIK, you're not doing anything illegal when you download copyright material (in Canada, anyways). It's only illegal to upload copyright material. Again, I believe that's the case, so if I'm wrong, feel free to correct me! Knowledge is power!
