It's all down to who commissions the program, and what the target audience is. In this case it's morning daytime TV who are the "customer" of the production team.
Now, according to the analysts, the average morning TV viewer is not one to sit around and watch TV., (s)he is running around doing the washing, wiping the kids noses, hoovering etc. and just "dipping" in and out of the telly. So the progs have to be structured to try and get the passing viewer's interest : so they either get a quick resume so they can pick up on what's already happened, or they get a "hook" of what's coming up in the hope they will plonk their bums down and continue watching.
These are 45 minute programs, but you can bet your ass that if they were on prime-team evening TV it would be 30 minutes with all the "slack" cut out. The reasoning this time being that people are actually wanting to tune in and watch. The first one did seem over-loaded with "coming ups " etc but the second and third seemed more content and less waffle.
It is quite possible that it will end up in an evening slot sometime in the future. That's what happened with Seaside Rescue apparantly. I get quite a few mid-week days off, but I never saw or heard of it until it appeared in the evening slot.
Don't expect too much blood and guts in the series though - this is feelgood TV where most people survive, designed not to spoil Yummy Mummy's day. Save that for "AA Uncut". Not to say that everybody will survive, mind : it is possible to lose a couple without too much viewer trauma.
