Is there anything on Britbox that I can't get anywhere else?

[TheBeeatAmbridge]

I've got a free trial of Britbox because I got a new phone deal, but don't want to sign up until it's worth it in terms of shows they have, to make the most of it. Already have Prime, Now TV and Netflix (but apparently there's 'nothing on', or so says DH ), so if any of you have got Britbox, what does it have that I won't find elsewhere? I tried looking at the website but I can't find an actual list.

We are currently watching downton abbey which we were only able to find on britbox

I watched Scott and Bailey (5 series) as I missed it when it was on TV, there is also something called The kindness of strangers which is quite old and I also missed which I want to watch but I have used up my free month on Scott and Bailey so I will have to wait until there are a few things on there to watch, maybe this thread will throw up some suggestions, so I can buy another month for £5.99, not tight at all
