my understanding, and I'm pretty sure they've said so, is that the next season of Fear is set after the end of the current season of TWD. So Fear is getting a quite hefty time jump aswell as a change of location that's also going to introduce a bunch of new characters
the first 2 seasons were a bit up and down, mostly down but still enjoyable enough, but season 3 really improved on the first 2 massively and was easily more consistently enjoyable and interesting than the last 2 or 3 seasons of TWD.
I can't help thinking crossing them over is going to be a case of 2 steps forward one step back, especially now Gimple's involved in it (even if it is in a position at the top of the creative food chain), but I'll give it a fair go and just see how it develops. Even if it turns out to be not as good as season 3 it could still end up better than TWD's been for the last few years without too much effort.
Cheers guys, I think I might try it out over the summer mths, work my way through it. For intrigue if nothing else. There will be a point when Billions, Legion etc finish and I'll be on the lookout for something. Have Twin Peaks from the very beginning to watch as well.
