I have gotten rather fond of the show. I found it unimpressive at first, and quit watching for a while, but then I gave it a second chance and came to appreciate it a lot more as the underlying mythology started to unfold.
The same for me as well. When it first aired on Showcase here in Canada, I think I watched the first couple of episodes, but it just didn't "click" with me and I gave it up. A month or so ago, Global-TV started airing it from the beginning and I decided to give it another try, and this time I enjoyed it quite a bit and have grown fond of the characters and mythology.
