I successfully pimped Firefly to my dad a few weeks ago. I'd been campaigning to see Serenity for weeks and finally my dad just told me to bust out my DVDs so he would know what the heck I was talking about. He ended up loving the series (we watched a dvd each day) and the movie when we saw it after finishing the DVDs. He would laugh and repeat lines and ask me about background things, and just a day or so ago he asked me about something he couldn't remember correctly. It was great to finally find something that my dad and I could both enjoy again, since he doesn't like Buffy/Angel or Stargate. We haven't bonded over a show like this since... hmm, maybe Star Trek?
