The Walking Dead is literally better than any Japanese manga kids like nowadays. The main reason for that is that Rick Grimes suffered more than Goku, Naruto and Saitama combined. Imagine waking up from a coma in the middle of a zombie apocalypse, being unable to find the people you love the most, having to find out that your own wife made love with your best friend (who also tried to kill you) and she's now pregnant, having to fight completely insane people doing disgusting shit, seeing friends and trustworthy people dying, having to fight a whole ass army, having your wife killed along with your newborn adopted daughter, seeing the guy who saved your life being beaten to death with a spiked baseball bat, marrying another woman and seeing her getting killed shortly, seeing your own son getting shot in the eye and ending up having one of the most boring deaths in the entire series. Don't you dare try to convince me otherwise, you'll surely fail.
