I watched that murder by text thing, I think its called Dark Phone, and thought it was decent overall.
Mu biggest criticism is what seems to happen with any program like this in that after every Commercial break and the start if every episode they spend ages going back over stuff that they have already covered so you actually don't get as much programme as you expect.
I know why they do it, its to bring the "Casual Viewer" up to speed so they can follow on even if they haven't seen the proceeding part or episode but its massively frustrating for those that watch the whole thing and are able to retain information to a reasonable level.
It happens more and more these days and I hate it!
