Finished it today and agree, the previous series felt like it had more humanity and believability, this one was still good but went a bit too much for tropes and increasing the body count (which I think is getting silly) over depth of story.
I've watched After Life over Christmas having not got round to it before and absolutely loved it - found it got the balance between humour and humanity absolutely perfect and couldn't stop watching. Can't wait for the next series now.
