Football violence
IMO the first 15 minutes of this film were more impressive than Football Factory, Green Street & The Firm combined.
In particular the underground scene was plain scary. I'd heard about Millwall and the surgical gear, but I'd always assumed that was mostly used as an effective way to conceal their identities. Seeing it here made me realize what an impact seeing 50 nutters in that get-up waving machetes must have had.
I am not a complete idiot. Some parts are missing.
