Very bad move especially as £10 is cheap for a BFI DVD, mine cost a bit more than that back in the day.

I rewatched Crooked House the other day and despite thinking that it wasn't bad on its original transmission it didn't really pass the test second time round. Compared to the '70s ones it's quite lacking. Still, better than nothing I say. Thanks Mark for sending me a copy.
