Before I discovered Breaking Bad I checked out the reviews on line. Never found a negative comment worth considering. It's an addictive show that is about addicts. I would recommend it to anyone.
Faults with the series? Well, it's a matter of opinion. In a well told unfolding and gripping story, it's less about the character portrayal (especially female characters) but this is a petty criticism (that I make) because that's not what I think it's trying to do. It depicts the characters as real-life and as deeply as is required to tell one great story with lost of emotional and intellectual twists, turns and tugs.
The best "TV" I've seen in a while and the best drama I've enjoyed too. Start at the beginning and watch it right through. There are spoilers out there so avoid them. Almost every episode was high intensity.
