Having never been to London, what I know of it comes from television and film: fish and chips, strawberries and cream; a love for tennis and football. They have funny accents and use weird words like 'bobby' instead of 'policeman', 'boot' for 'trunk', and 'shag' for 'sex'. And now, after watching Attack the Block, I know not to fuck with their inner city youth - especially if you're from another planet.
Do you like modern war movies, gritty action, alien invasions, Aaron Eckhart and (most importantly) do you really really like over-the-shoulder shaky cam? Do you not care for things like original dialogue, plotting, or characters? If this describes you, then Battle: Los Angeles is what you should be watching right now.
