Yikes. Rats? Bugs?! I think you need to find better cinemas! At least around here (London), I'd say the cinema experience is massively better than it was even 5-10 years ago. Lots of cinemas - pretty much all of the big chain ones - upgraded with better seating, much bigger screens, better audio, better food & drink offerings, etc. The smaller independents that haven't upgraded usually offer cheap ticket prices and other enticements like good local craft beer
Some, like IMAX etc, have truly enormous screens and amazing audio that most of us are never going to replicate at home.
