All in all, the show grew on me. I'm a fan of long arc stories, so once the series settled into giving us more and more hints about Audrey, Nathan, and the "troubles," the show seemed to become more than just a weirdo of the week. I'm looking forward to seeing what happens with all the new revelations next season.
Speaking of weirdo of the week, I've just watched the first 4 eps of the new Fringe season, and am really liking it. The creators took the time-honored route of creating 2 versions of Olivia, the main character. One is in our world and the other is in an alternate world. This allows one Olivia to pursue a relationship with Peter, while the other one is pursuing other things--like her mind, which apparently she's lost.
