I am looking at starting Fringe - heard so many good things, but never got around to it!
Season 1 is very monster of the week and I struggled to get into it multiple times. However power through and it hits it's stride seasons 2/3 then drops off in quality. The less said about season 5 the better.
Walter Bishop is amazing though, he comes out with some cracking lines and some of the things he gets up to in the lull between stories had me chuckling a fair few times.
