DH and I aren't big TV watchers at all but in an attempt to wean the DC off their YouTube crap and have a bit more family time we decided to start watching a series together.
We picked Ludwig and all thoroughly enjoyed it. Enough to keep DH and I gripped but tame enough not to distress DD9 and DS11. The DC loved the whodunit element and trying to work out the culprits.
Is there anything else along similar lines that people could recommend? We've got Netflix, Prime and the usual freeview stuff.
