I agree it would be truly sad to see Fringe go. Being a TV addict, I read TV Line daily. There are already pieces quoting Fox management who are proud of what the makers of Fringe are putting out there but, alas, the show is losing money. Ratings from last Friday were steady but they'll have to have an uptick to attract advertisers & I doubt that such a complicated show as Fringe, which one can't simply watch for the first time in season 4 & understand everything, will gain many new viewers in the next few months.
Last hope will be meetings between Fox & the show's production company this Spring. If I'm reading the tea leaves correctly, though, season 4 will be the last broadcast TV episodes of Fringe. The makers are already saying that the season 4 finale can stand as a series finale, but they did the same for season 3 as ratings were not great last year either. Fringe was only saved by the production company making a sweetheart deal with Fox.
If it does go off TV, they are already talking about continuing via webisodes which I imagine all acting talent will participate in because how many opportunities do actresses & actors get to play so many versions of the same characters?
Such is life in the business of show. At least we still have great shows like White Collar, Game of Thrones, Suits, Breaking Bad (for 2 more half seasons), The Walking Dead, The Good Wife, American Horror Story, Sons of Anarchy, True Blood, Californication, Dexter, Homeland & Shameless (totally awesome). I don't know if Luther will be back for a 3rd series but that, and the UK Sherlock, are both very good as well. I only hope I can sort my Flash issues so I can keep watching them all on VIPTV.
