• First, this is the sort of flick the UK writers do so well and frankly don't do enough of.

    Reminds me of the old saying, when Life gives you Lemons, make Lemonade.

    London has blessed the UK film industry with one of the most diverse and interesting ecosystems on the planet. What, I have lost count, 14 distinct accents and counting? In return the industry has taken this raw material and produced a wide range of thrillers, most of which rely heavily for their impact on the violence element or the gang element.

    So, who woke up one morning and said, hey, let's make the gang the good guys for a change ... instead of causing trouble they get to defend the country against aliens. And brimming with gang values, they will go it alone, they will not even ask for help.

    Great premise, brilliant and engaging execution. It could have just been "merely" entertaining, but great writing, cast, acting and direction help it make the leap to cult classic.

    The low IMDb rating is not merely wrong, it is seriously wrong. This is a fun film that can be watched more than once.
