In every generation there must be a silly TV series about the supernatural which does not aspire to be anything other than entertaining. Or at least there ought to be one. Ghosts, which is available on the BBC iPlayer here, is a good example of a comedy that plays with familiar haunted house tropes and pretty much gets it right. It's not scary (because it's a comedy) but it is enjoyable if you put your brain in neutral and simply watch what happens. If you've seen Horrible Histories, it's the same kind of thing only with a slightly more adult slant, hence it's relatively late time slot.
The premise is the time-honoured gimmick whereby a very, very distant relative of a deceased toff inherits a big country house. Alison (Charlotte Ritchie) is the inheritor of the crumbling Button Hall. She and her boyfriend Mike (Kiell Smyth-Bynoe) plan to renovate the hall and turn it into a posh hotel. But Alison has a near-death experience that leaves her able to see ghosts - and the house is full of them.
