I liked "Wonderfalls" as well. The first ten minutes or so, I wasn't sure about it, and I sat there with the remote in hand, wondering why I wasn't changing the channel. But after those first few minutes, I decided that I really liked the show. I agree that the main character is quirking and original. So is the writing. "Wonderfalls" is squarely in the tradition of the sort of slightly-off-center comedy that FOX has become known for. Starting with "Married: With Children" and continuting on through shows like "The Simpsons", "King of the Hill", "Futurama", "Malcolm in the Middle", "MAD-TV", and "Arrested Development", FOX has consistently aired the funniest comedies on TV, in my opinion.
I imagine that I'll be watching "Wonderfalls" again, so long as the local FOX affiliate doesn't rebel and quit showing it - the ownership has been in the forefront of the current campaign to "save America from indecency" by vociferously adovcating passage of the Broadcast Decency Enforcement Act of 2004. In other words, they are quite willing to act as Big Brother, given the opportunity. Aarrrgh.
