Those deep-fried rings are tasteless. Try it as sashimi in a place where the chef knows enough to score the top of it to make it easier to eat. Actually, it’s still tasteless but has an intriguing texture raw. Some people hate it raw too.
Thinking of squid, though. Not octopus.
I’m not terribly brave, but our chef made me try a full bite of Ahi tuna seared rare and though I thought I would gag, I absolutely loved it. It’s now my favorite thing on the menu. Squid, though...I just don’t know.
