You have to see Breaking Bad before moving on to Ozark cause it's like watching the fake from the real thing. Without AMC's classic crime drama, Ozark won't exist because it's considered to be the top 10 series of all time.
They have similarities due to the fact that Bryan Cranston played a man thrust role into the crime game (making and selling meth) under dire circumstances (he has terminal cancer and wants to provide for his family), creating the foundation on which Ozark was based.
Breaking Bad is superior to Ozark due to the great performance in writing, directing, and acting on perfecting the high-wire intensity that many shows have since tried to emulate. Cartels, money laundering, a family on edge, it's all here in Breaking Bad, and it's much better.
