Got to say, some of their displays were amazing and really helped generate an atmosphere at what is a morgue at times these days. The European nights a couple of seasons ago were superb, and their tribute to the helicopter victims was quite something.
While they appear to have had some cretins in their group (e.g. the boy with the flare), some were far too quick to criticise the Red Ultras who at least make some attempt to liven up the atmosphere.
