Things really only go wrong, for me, in the last half hour. Is it the hotel that is weird or just the people? Jon Hamm is great in the early stages and looked a bit like a young Robert de Niro. beautifully shot and confidently and surely constructed to have us spellbound but not fully aware of just what is going on.

For the most part this is a really good, if not excellent film, with a fantastic central performance from Jeff Bridges, ably supported with an equally compelling performance from Londoner Cynthia Erivo who I recently saw in Stephen King's The Outside TV series.
