Bleak, very bleak. It's set in London's version of a dystopian car-centric industrial future, and everyone working or patronising this cinema looks like they've given up on life. This cinema is best avoided unless you're desperate or have a Cineworld voucher that you simply can't use anywhere else.
Tucked away in a barren industrial pocket on the North end of the North Circular, just off the A5, is this fairly large sized and only slightly decrepit Cineworld multiplex. It is a hideaway for the North London cinephiles, the only place to go when all the decent cinemas are booked up for that weekend's hottest film. Staples Corner Business Park is rarely visited by people from outside of the area - Brent Cross is just up the road, the transport links aren't great, and it is is generally isolated and crime-prone. Regardless of these pitfalls, it is always there and can always be relied upon when tickets can't be found anywhere else.
When I last visited, the central heating in two of the screens had failed, and since it was -2 outside this made for a chilly viewing. However, because the film in question was The Revenant - which is set in the wintry climes of Upper Missouri - it sort of made sense and I would go as far as to say that it enhanced the experience. It was if the cinema's manager knew this would be the case, and turned off the boiler to ensure that everyone could fully immerse themselves in the struggle of the protagonist.
There was only one time that Cineworld Staples Corner let me down, and that was during the London Riots of 2011, when the staff had barricaded the windows and glass panels with ten foot high steel fences in preparation for an onslaught of looting which never came. That was fair enough.
