I complained about the cine-mice at Shaftesbury Ave. I'm not sure they believed me. That's by far the worst CW I've been to.
My CW rundown...
Ashford - nice, quite new, lots of nice big screens
Rochester - one big screen, and 8 smaller ones. Most equipped for digital, though
Bexleyheath - sad little CW with no box office during the week, no big screens, poor picture quality, and a tendency to leave the house lights on
West India Quay - best of my local CWs
WanRABworth - big, big CW above the shopping centre, with big, big queues
Enfield - 15 screen giant on the A10. Enormous queues and sticky floors
Chelsea - tiny CW with tiny screens and sixties feel
Fulham Road - 6 screen large victorian conversion (best of the older CWs)
Edinburgh - modern CW with 1 IMAX screen
