Fringe: worth persevering?

[whyKT]

I think season 3 is really good if you stick with it to the finale. I was so excited for season 4 but lost interest midway as it seemed slow after the big story arc ideas of the first 3 seasons. I should really catch up

Love fringe first four seasons were good. Watching the fifth on sky now and not sure about this season hopefully it will improve

I started to watch this when it came out, and although I enjoyed it I found the format tedious and expected the cancel hammer to swing.
I stopped watching it, and I have not felt the need to return.
