I'd welcome a cinema an can't really complain about the Capitol closing as I've been in less than 5 times in the 8 years I've lived in SE23.
As for the atmosphere I found it fine, in fact as a whole I find Wetherspoons have great atmospheres. No music means you can have great conversations with friends - they have often been in my younger going out years a default meeting place for a catch-up all on reasonably priced drinks. What's not to like?
