1. Be patient. The Wire is often referred to as "the televisual equivalent of a novel", partly because that sounds flouncy and impressive, but mainly because it's structured like one. Think of each episode as a chapter in a book. It's important to bear this in mind because years of TV watching will have conditioned you into expecting a neat, processed conclusion at the end of any given programme. This first instalment is merely putting characters and themes in place for the rest of the season. The show is a textbook "slow burner" - don't expect to have your world altered by a single chapter.
2. Concentrate, without breaking a sweat. The Wire is more realistic than any other "cop show" you've ever seen. It was created by a former crime reporter and a former homicide detective, so it knows its subject matter inside out. Consequently, the police and the dealers regularly use insider slang without explaining what they mean. Stir unusual Baltimore accents into the mix and you might not understand everything they're saying. No matter. You'll pick it up. Before long, you'll be an expert.
3. Prepare to obsess. No other show on TV has such an impressive range of intricate characters. Give them a chance and they grow on you like moss. I know heterosexual men who are deeply in love with Stringer Bell. Once you "get into" the show, it's impossible to get out, and at the end of each season you'll be jonesing, junkie-style, for your next fix. So get ready to bore your friends by droning on and about its brilliance. Like I'm doing here. Anyway, just watch the bloody thing, will you?
