I watched the first season of
Fringe, and while I thought I was enjoying it at the time, in retrospect there is really only one character of interest on that show: Walter.
Now granted, Walter is a GREAT character. A REALLY great character, in fact. But the rest of the characters are only average...and Olivia, to me, is outright annoying.
I haven't watched any of season 2 yet...I'm almost afraid to devote any more time, given that it will likely be canceled and won't get a decent ending.
