IMO People that compare it to Lock and Snatch are missing the point. Lock and Snatch are "cartoony" films. Larger than life characters and some real life villians thrown in for good measure. Lots of action, lots of bling.
LC is more how it is in real life. The quote about Wannabee Gangsters is spot on! You want to make a career in selling Drugs. You HAVE to keep low profile. The RS6 in the film is a perfect example. No dealer who wanted to be low profile would have a BMW, Jaguar,a Chelsea Tractor or a Merc, too flamboyant, too showy.
I like it for that. Plus it makes London look quite nice
