Fringe has had a weird run on television. It has always been critically acclaimed but had a hard time finding an audience.  Despite the high quality and interesting sci fi storyline there has been the threat of cancellation hanging over it almost from day one.  All this to say that if you have not watched the show so far because of a perceived lack of big numbers equaling an inferior product then you could not be more wrong if you are a fan of this type of television.  This kind of television being an interesting mix of The X-Files and CSI. The fourth season is all about the big set up for the series announced final season – the fifth.  Engaging, quirky and different from most everything else on television, Fringe is certainly worth the time investment.
