Any anime you thought you would hate but loved it?

[Kαmi]

Definitely One Piece. At first glance, I thought it was going to be too childish and not interesting enough but I was completely wrong. The art made me skeptic at first but now I admire it. I'm glad I gave it a try.

SAO kinda fits that picture. I thought I'd hate it but it turned out alright.

Code Geass, because mecha. I also never thought I'd enjoy HxH as much as I did.

 

[Hattake Ryuzaki]

Kill la kill

 

[Amaterasu]

Hunter x Hunter. The old manga cover had a picture of Gon with a fishing rod and a large frog, I think.
Assumed it would be about some kid catching weird creatures, kinda like Pokemon. Lol

Haha the same and the name was weird too but know this manga is Number in my Top List.
