With The Wire I think what made it was the many unique and fully fleshed out characters if you didn't appreciate or pick up on that aspect then you might wonder what the fuss was about. Better to watch it without thinking about the hype and let yourself become immersed in it, it is apparently very accurate/true to life as to how things actually are in those parts and I think that's why alot of people loved it, it seems so real and believable once you're hooked in. One of the female gangsters was actually an ex gang member and ended up going back to that life after it was done, that's pretty authentic method acting for you there.
