1. He's one of the least believable world champions, just look at him, it's not believable that this little midget is like a 10 time world champion
2. People dont hate him because 'he's a good heel", they hate him because he stinks
3. Terrible in the ring, he doesn't do anything, no memorable matches
4. No character
5. Because he has no character, his WrestleMania 27 entrance was giant balloon letters that said "Awesome", the Undertaker or Triple H have character so they had gimmicky entrances, The Miz has no character so thats all they could come up with
6. He doesn't look like a wrestler, he's out of shape skinny fat
7. All of his theme songs are terrible
8. He gets no reaction when he comes out, because nobody cares
9. He's gay
10. His horrible feud with Cena
11. The worst WrestleMania main event
12. He's so boring
13. Maryse is the only good thing about him
14. His finisher is horrible, doesn't look like it hurts
15. I usually say "his fans suck", but Miz has no fans lol
